The earlier design was to take whatever non-alnum that the short format
parser happens to support, leaving the rest as part of the pattern, so a
version of git that knows '*' magic and a version that does not would have
behaved differently when given ":*Makefile". The former would have
applied the '*' magic to the pattern "Makefile", while the latter would
used no magic to the pattern "*Makefile".
Instead, just reserve all non-alnum ASCII letters that are neither glob
nor regexp special as potential magic signature, and when we see a magic
that is not supported, die with an error message, just like the longhand
codepath does.
With this, ":%#!*Makefile" will always mean "%#!" magic applied to the
pattern "*Makefile", no matter what version of git is used (it is a
different matter if the version of git supports all of these three magic
matching rules).
Also make ':' without anything else to mean "there is no pathspec". This
would allow differences between "git log" and "git log ." run from the top
level of the working tree (the latter simplifies no-op commits away from
the history) to be expressed from a subdirectory by saying "git log :".

Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX
5.1 fails to compile git.
enum style is inconsistent already, with some enums declared on one
line, some over 3 lines with the enum values all on the middle line,
sometimes with 1 enum value per line... and independently of that the
trailing comma is sometimes present and other times absent, often
mixing with/without trailing comma styles in a single file, and
sometimes in consecutive enum declarations.
Clearly, omitting the comma is the more portable style, and this patch
changes all enum declarations to use the portable omitted dangling
comma style consistently.

Add is_regex_special(), a character class macro for chars that have a
special meaning in regular expressions.

Replace isspecial() by the new macro is_glob_special(), which is more,
well, specialized. The former included the NUL char in its character
class, while the letter only included characters that are special to
file name globbing.
The new name contains underscores because they enhance readability
considerably now that it's made up of three words. Renaming the
function is necessary to document its changed scope.
The call sites of isspecial() are updated to check explicitly for NUL.

Enhance the readability of ctype.c by using an enum instead of macros
to initialize the character class table. This allows the use of a single
letter to mark a char, making the table fit within 80 columns.
Also list the index of the last entry in each row in the following comment.

The following syntax:
char foo[] = {
[0] = 1,
[7] = 2,
[15] = 3
};
is a c99 construct which some compilers do not support even though they
support other c99 constructs. This construct can be avoided by folding
these 'special' test cases into the sane_ctype array and making use of
the related infrastructure.

Some platforms contaminate the preprocessor token namespace with their own
definition of SS without being asked. Avoid getting hit by redefinition
warning messages by explicitly undef SS, AA and DD shorthand we use in this
table definition.

This uses "git-apply --whitespace=strip" to fix whitespace errors that have
crept in to our source files over time. There are a few files that need
to have trailing whitespaces (most notably, test vectors). The results
still passes the test, and build result in Documentation/ area is unchanged.

Do our own ctype.h, just to get the sane semantics: we want
locale-independence, _and_ we want the right signed behaviour. Plus we
only use a very small subset of ctype.h anyway (isspace, isalpha,
isdigit and isalnum).
