Hmmph.  This actually comes up incorrectly on my system.  The issue
appears to be `git --exec-path` gives me $prefix/libexec/git-core,
and git-gui installs its library into $prefix/libexec/share, which
is wrong.  It should have gone to $prefix/share.

I wonder if this is better.  Your other two patches seem fine.

[PATCH] git-gui: Correct installation of library to be $prefix/share

We always wanted the library for git-gui to install into the
$prefix/share directory, not $prefix/libexec/share.  All of
the files in our library are platform independent and may
be reused across systems, like any other content stored in
the share directory.

Our computation of where our library should install to was broken
when git itself started installing to $prefix/libexec/git-core,
which was one level down from where we expected it to be.
