[PATCH v8] git-p4: Obey core.ignorecase when using P4 client specs

I realized after reading the mailing list that my v7 was signed off twice. I fixed that in v8.

Sorry for the spam,
Lars

[PATCH v8] git-p4: Obey core.ignorecase when using P4 client specs

larsxschneider
From: Lars Schneider <[hidden email]>

Perforce depot may record paths in mixed cases, e.g. "p4 files" may
show that there are these two paths:

   //depot/Path/to/file1
   //depot/pATH/to/file2

and with "p4" or "p4v", these end up in the same directory, e.g.

   //depot/Path/to/file1
   //depot/Path/to/file2

which is the desired outcome on case insensitive systems.

If git-p4 is used with client spec "//depot/Path/...", however, then
all files not matching the case in the client spec are ignored (in
the example above "//depot/pATH/to/file2").

Fix this by using the path case that appears first in lexicographical
order when core.ignorcase is set to true. This behavior is consistent
with "p4" and "p4v".
