Didn't apply cleanly? Looked fine though so I manually put it in.

I don't know about this. The fix is simple enough, but a much better
policy is to *never* use uppercase for any reason whatsoever when
working with idtech3 on non windows operating systems.

Windows filesystem, for which the game engine, level editor and map
compiling tools were primarily developed is case insensitive (although
case "aware"). When files are packed into zip (pk3) files it just so
happens that the file search is case insensitive as well on non-windows
operating systems.

Still if you try to work with an expanded assets tree for day to day
level design and game production work with tech3 and GtkRadiant on a non
windows operating system, you will risk many subtle problems if you have
files and paths with uppercase letters.

This fix is really only the tip of the iceberg and I'd rather not go
there at all. Our policy at id is to refuse checkins to baseq3/ if some
files have uppercase letters (which can be easily enforced with a commit
hook script in subversion).
