Find attached a patch that implements both GLOBAL_OPTIONS (marking
GTAGSTHROUGH as deprecated) and --color=never|always|auto (-C and --color
are the same as --color=auto) for 6.2.10 (based on my previous doswin.txt
patch, but I expect it should work for the original release; as with that
patch, I've only supplied manual.in, not any of the generated files, but
my site[1] has them).  Given the above example, I've also added
-E,--extended-regexp, -m,--match-case and -S,--project to allow overriding
of GLOBAL_OPTIONS, restoring defaults.

For DOS and Windows (including Cygwin), GLOBAL_OPTIONS will translate
'~' to '=', to be compatible with COMMAND.COM (which doesn't allow equal
signs in variables).

Windows users wanting to build it themselves will still need ANSI32.dll
from ANSICON[2] for color support (my binaries come with it).
