Re: Intensive rename detection

["Andrew Arnott" <andrewarnott@gmail.com>]

Awesome.  Per Linus' tip, I just noticed at the top of a long list of
messages git said:
warning: too many files, skipping inexact rename detection

So I added the config file change, and that did the trick.  Thanks, everyone!

Here's a related but slightly different question: I've been stashing
and unstashing in the midst of all these renames and refactoring, and
now I'm left with some files listed in git status 3 times.  I
understand why this is, but I don't know the best way to proceed.  Git
is telling me:

$ git status | grep MessageBase
src/DotNetOAuth/Messages/MessageBase.cs: needs merge
src/DotNetOAuth/OAuth/Messages/MessageBase.cs: needs merge
src/DotNetOpenAuth/Messages/MessageBase.cs: needs merge
#       unmerged:   src/DotNetOAuth/Messages/MessageBase.cs
#       unmerged:   src/DotNetOAuth/OAuth/Messages/MessageBase.cs
#       unmerged:   src/DotNetOpenAuth/Messages/MessageBase.cs

I want to end up with MessageBase.cs in
src/DotNetOpenAuth/OAuth/Messages/MessageBase.cs, which ironically is
none of these three.  And the couple of lines that changed in the file
need to be merged.  Only two of these listed files exist on disk.  How
can I best leverage git to merge the two files on disk while moving it
to a new location?
