Oops - that was an oversight on my part.

The reason for that was so that e.g. "tif" can match .tif and .tiff and
other usage cases like that. The original usage for G_basename() was
checking the output filename for r.out.tiff so it could decide if it
should add an extension or not.

That would break the way it is used in r.out.tiff in some circumstances.
I'm thinking it might be easier to conditionalise its use in G_parser()
and G_set_program_name() on __MINGW32__ as its only purpose there is to
strip out the .exe executable extension on Windows?
Maybe there should be two functions though. Or maybe stripping out the
.exe is quite simple and it doesn't need to use G_basename()?
If noone else has fixed this yet I'll try and get to it fairly soon.
