If the position of the cursor changes horizontally,
placewewant should change with it.

Dereferencing a NULL pointer is never a good idea.

Eradicate the need for backslashes, so that the start of the nanorc
manual becomes true, where it says that quotes inside strings don't
need to be escaped. In the bargain achieve that the empty string
always switches commenting off.
This fixes https://savannah.gnu.org/bugs/?51370,
and fixes https://savannah.gnu.org/bugs/?51394.
This avoids some warnings when compiled with -pedantic:
ISO C forbids comparison of ‘void *’ with function pointer
ISO C forbids empty initializer braces
When the active syntax contains a comment command that specifies the
empty string, this should override the default comment of "#" and
should disable the Meta-3 keystroke.
To achieve this, the comment string is now set by default to "#" for
all syntaxes, so that it will be set when no comment command is given
(including for the "none" syntax), and is unset only by explicitly
specifying «comment ""» in a syntax file.
This fixes https://savannah.gnu.org/bugs/?51355.

When also --nohelp is active and the terminal is so narrow that the
message that --constantshow displays on the bottom row does not fit,
this causes the cursor to be pushed "offscreen". Some terminal
emulators don't handle this case correctly, and leave the cursor
in an invisible or mistaken position. Compensate for this by
moving the cursor back to the start of the row.
This fixes https://savannah.gnu.org/bugs/?51335.

The extra variable is not needed, because when having read from
standard input, the filename will simply be empty. It will not
be empty for any other file that was read.
The dash doesn't have to be the first non-option argument: it can
be anywhere among the filenames -- there can even be multiple ones
(but don't mention this explicitly).
Negative arguments of 'fill' are bright green since a few commits.
So now color all valid numeric arguments in that same style -- the
yellow was hard to see on a dark background anyway.
Also, color a zero tabsize as invalid.
A recent change (8dffb00f) removed this ability. This change restores
it, and also allows reading from standard input multiple times -- maybe
not useful, but it works.
