- The TortoiseGit team renamed TortoiseMerge.exe to TortoiseGitMerge.exe
  (starting with 1.8.0) in order to make clear that this one has special
  support for git and prevent confusion with the TortoiseSVN TortoiseMerge
  version.
- The tortoisemerge mergetool does not work with filenames which have
  a space in it. Fixing this required changes in git and also in
  TortoiseGitMerge; see https://github.com/msysgit/msysgit/issues/57.

The new tortoisegitmerge helper was added so that people can still use
TortoiseMerge from TortoiseSVN (and older TortoiseGit versions).
