[PATCH] mergetools: Enhance tortoisemerge to work with

[Sven Strickroth <sven.strickroth@tu-clausthal.de>]

TortoiseGitMerge and filenames with spaces

- 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, (uses spaces as cli parameter key-value separators)
  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.
