Looking at case insensitivity - question

[Jens Alfke]

FYI, I asked on one of the Apple developer mailing lists about system  
calls for converting a filename or path to the canonical case; the  
answer is that there is unfortunately no standard (POSIX) call, such  
as realpath, that has this effect on Mac OS X.

A few ways to do this using Mac-specific APIs were suggested. I  
believe these could be implemented in Mercurial without having to  
write any C extensions, using the Mac OS's built-in bridging support.  
It would of course require some Mac-specific Python code, but this  
could be isolated in a separate module and loaded conditionally after  
a platform check. Any Windows-specific equivalent could be treated the  
same way, of course.
