Trouble with case-insensitive filesystems

[Rocco Rutte <pdmef@gmx.net>]

Hi,

after importing the opensolaris hg repo into git, I noticed that git 
gets confused if the repo contains files that clash on case-insensitive 
filesystems (here on OS X, I can't test Cygwin and Win32). git-checkout 
tells me that these files are modified, git-status gives me:

$ git status
# On branch master
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#
#       modified:   usr/src/cmd/lp/filter/postscript/font/devpost/HB
#       modified:   usr/src/cmd/lp/filter/postscript/font/devpost/HB.name
#       modified:   usr/src/cmd/lp/filter/postscript/font/devpost/HI
#       modified:   usr/src/cmd/lp/filter/postscript/font/devpost/HI.name
#       modified:   usr/src/cmd/lp/filter/postscript/font/devpost/HX
#       modified:   usr/src/cmd/lp/filter/postscript/font/devpost/HX.name
#       modified:   usr/src/cmd/lp/filter/postscript/font/devpost/charlib/LH
#       modified:   usr/src/lib/libldap4/common/Version.c
#
no changes added to commit (use "git add" and/or "git commit -a")

...without touching anything. Yes, there's a version.c file next to 
Version.c, HI.name next to Hi.name and so on.

I'm not really sure what I'm expecting git to do, but I guess I want it 
to abort a checkout and only continue with -f. But at the very least, it 
should issue a big fat warning (one may decide to work in some area 
without clashes).

I really have no idea how to efficiently detect that at runtime and 
which areas of git to look at for patching...
