ac102a7516 tweaks: show "Space" and "Bsp" in the help text of the browser 
These keys make more mnemonic sense for scrolling than F7 and F8.

Also adjust the nanohelp syntax to cover the lone word "Space".

by spaces to not color the ones in shell fragments), and add some
comments.

22663f8a2e syntax: makefile: recognize also an all-lowercase makefile name 
Recognize not just "Makefile" but also "makefile" and "GNUmakefile".
And recognize these only when they are the full filenames, not when
they are the tail part of a longer name.

When 'afterends' is set and Ctrl+Right or Shift+Ctrl+Right is pressed,

38a10a62d0 syntax: lua: support fractional part and exponent for decimal and hex

part plus an optional binary exponent, marked by a letter 'p' or 'P'"
(see at the end of https://www.lua.org/manual/5.2/manual.html#3.1).

The new regexes do not match a leading nor a trailing dot, but they

4761e00852 syntax: nanorc: don't color parts of valid strings as if invalid 
It's better to color some invalid things as if valid than the other
way around.  So, as strings can validly contain any number of double
quotes, just accept *anything* between the delimiting double quotes
and demand that the closing quote is followed by whitespace or EOL.

bacb0f717d syntax: adjust the magic strings for the changes since file-5.10 
Since file-5.10 (end of 2011), libmagic identifies a C file in most
cases as "C source" instead of as "C program".  Nano's magic strings
for some other files didn't match any more what file-5.32 currently
produces, either.  So, they have been adjusted, new ones added, and
old ones deleted.
