Subject: [PATCH] Ignore duplicated slashes in git-log
Message-ID: <20080209125457.GA5686@basil.nowhere.org>

```

When I use git-log ... path/name  I seem to regularly
typo path/name as path//name (with duplicated slashes)
The normal kernel ignores these duplicated slashes
according to POSIX so it's typically no problem, but git 
fails and cannot find the correct file name when this
happens.

This patch fixes this case for git-log at least, by
handling duplicated slashes as a single slash. I probably
didn't change all places where file names are parsed
in the source base, but this seems to be a relatively common
place used by several sub commands. And at least for me
fixing git-log is the most important case anyways.

Patch against git 1.5.4

This is only one case you want to fix.  There are absolute paths, too, and 
series of "../".

Alas, Junio was quicker than you:

It's hard to imagine anyone typoing sequences of ../ or ./, so at least
I personally didn't feel the need to handle that.
