"hg mv" cannot change case on windows, and "hg status" does not notice it either

[Bill Barry]

The operating system cannot always just change the case of a file.

powershell:

Posh C:\hgwork\Website> echo test > test.txt
Posh C:\hgwork\Website> rename test.txt Test.txt
Posh C:\hgwork\Website> ls


    Directory: Microsoft.PowerShell.Core\FileSystem::C:\hgwork\Website


Mode                LastWriteTime     Length Name
----                -------------     ------ ----
-a---          6/5/2009  11:57 AM         14 test.txt

though this same test works in a command prompt...

in explorer I get an error when I try to change the case of a file; I 
have to rename it to something else and then rename it to the final name.


The simple answer is that case sensitivity in file systems is simply 
broken in Windows. Some places it works, some places it doesn't. Nowhere 
does it work 100%. It could be a Mercurial bug, a python bug or a 
Windows bug.
