2181853574 syntaxes: use character classes instead of range expressions 
In some locales certain normal ASCII characters are not included in
the ranges [A-Z] and [a-z].  So, use [[:upper:]] and [[:lower:]]
instead, and [[:alpha:]] for [A-Za-z], and similarly for others.

This fixes https://savannah.gnu.org/bugs/?67094.

fabc1e1219 syntax: default: show hard spaces with a lightgrey background 
Some keyboard layouts allow typing hard spaces (U+00A0),
which means that sometimes they can get typed by accident.
Colorize those spaces to make such accidents noticeable.

95731b800d options: accept --whitespacedisplay and 'set whitespacedisplay' 
Allow some people to use 'set whitespacedisplay' in their rcfiles
(or --whitespacedisplay on the command line), but leave the option
undocumented as I think it shouldn't exist.

1862995aab syntax: spec: colorize all canonical architecture names 
The list of canonical names was found in:

The canonical names were extracted with:

  grep arch_canon rpmrc.in | sed 's/^.*:\s*//' | sed 's/\s*..\?$//'

and then sorted and condensed into a regular expression.

For some files the original author is unclear, or
the file is/was too small to mention an author for.

02dd0b4ed5 options: require --colonparsing/-@ to parse colon+number after a filename 
Stop doing colon parsing by default, to avoid surprises and frustration
for users that have filenames that end in a colon plus digits.

The equivalent rcfile option is, of course, 'set colonparsing'.

Using +1, or similar, before the filename disables any colon parsing
and the filename is taken as is.

c02aec557c syntax: makefile, sh: recognize also a fresh Makefile and fresh .profile 
When opening a nonexistent file with nano, it likely consists of only a
name without any path component, and thus without any slash.  So when a
file regex checks for a slash, it should check also for start-of-string.

This fixes https://savannah.gnu.org/bugs/?65591.

Problem existed for the Makefile since version 2.9.8, commit 22663f8a,
and for .profile since version 3.0, commit 4a268678 (but earlier, nano
did not recognize .profile files at all).
