2535f51e01 statusbar: prevent error messages from overwriting each other
If during startup there are multiple error messages, currently only the
last one remains and can be read.  To improve on that, introduce a short
pause between error messages -- even if it's not enough to read them all,
at least the user will be aware that there are multiple ones.

This also causes a few error messages to beep that currently don't beep,
such as when a file is unwritable.

58404e4ba2 browser: keep the highlight in the same spot or column, when possible
When doing a PageUp or PageDown in the browser, don't move the highlight
to the first line in the same column, but keep it in the same relative
position of the screen.  If we're already on the first or last page,
move the highlight to the first or last line, but keep it in the same
column.  If we're already on the first or last line, only then move it
to the first or last entry.

8a5b4f616b browser: keep the same file selected when the directory contents change
When refreshing the screen (and thus the file list), use the prev_dir
mechanism to reselect the file that was selected before the refresh,
to prevent the selection from changing when files were added or deleted.

Also, when the selected name has disappeared, move the highlight one step
back, so that it is obvious that the selection has changed.  (Decrementing
'selected' will never make it negative, because selected == 0 means the
'..' entry, and every directory has a '..' entry, so it will be found.)

This fixes https://savannah.gnu.org/bugs/?47812.

9cbe6a640c search: when polling the keyboard, consume all waiting keystrokes
When during searching we look at the keyboard, then don't look at
just the first keystroke, but check if there are more, and if so,
check each one until we find a Cancel -- or until all keystrokes
have been consumed and we can continue.

This fixes the first half of https://savannah.gnu.org/bugs/?47438.

c918c6563b input: properly restore waiting mode, or retain non-waiting mode
Cancelling a search should restore waiting mode for the keyboard,
just like at the other exit points of the search routine.

And when the input routine has read in multiple keystrokes, it
should not blindly switch back to waiting mode, but only when
that mode was on before.

577f7fafa9 screen: make better use of the available space in the titlebar
When the terminal is very narrow, there is little point in showing only
part of the version string -- and chewing off one or two digits from the
version number might even give someone a wrong idea.  The user is better
served with always showing the full filename, as long as it fits in the
available screen width.

be4a3f8273 spelling: separate the fixing of different words with a short pause
When fixing a misspelling and not answering 'All' (but 'Yes' or 'No'),
the chance is quite substantial that one will type y or n at the end of
the next word.  Diminish this chance by showing for a moment a message
on the statusbar.

433c7e5dc6 spelling: don't partition the file for replacements in a marked region
Partitioning the file makes the undo system lose track, so that undoing
things has a good chance of losing data.  Instead, just make sure that
the region is marked "backwards", with current at the top and the mark
at the bottom, and then let the replace loop take care of not going
outside of the marked region.

This also has the effect that if the marked region fits entirely on the
screen, or all the misspellings are onscreen, then the screen will not
be scrolled at all.  Which makes for a smooth experience.

318ed6b105 scrolling: center the cursor when inserted stuff does not fit on screen
Since nano-2.4.1, reading in or pasting a large piece of text would put
the cursor on the bottom line, leaving only one line of the non-read or
non-pasted text visible.  This is different from the centering behavior
of Pico, and somewhat disorienting, as you can't see "where you are" any
more in relation to the file as it was.

So now center the cursor whenever the read or pasted text is larger than
the screen, but don't center it when the text fits entirely on the screen.
(The latter avoids the effect of the screen jumping unnecessarily when
inserting just a few lines while the cursor is near the bottom.)

To achieve this behavior: default to focusing, and temporarily set it to
FALSE when the focusing effect is unwanted.

7b3649abc9 input: don't take multiple keystrokes to be a single sequence
For some reason the keyboard code seems to assume that all integers
waiting in the keybuffer form a single sequence.  But this isn't the
case: when there is an escape (0x1b) among them, then that is where
a new sequence starts.  So, prevent the input code from considering
an escape after a non-escape as part of the current sequence.

(when begin == NULL) but simply ignore its value.

The internal spell checker starts searching/replacing always at the top

from flashing over the statusbar at the end of a spelling replacement.

9f1a44d9e3 replacing: properly detect when we've rereached the starting position
Commit 8704dde mistakenly removed this part of code -- it is not dead,
it is just that it will only fire when the user answered No at some of
the replacement prompts.  So... when we've rereached the starting line,
a found occurrence is invalid when it is beyond the starting x (either
after or before it, dependending on the direction of search).
