* 'master' of git://repo.or.cz/git-gui:
git-gui: apply color information from git diff output
git-gui: use wordprocessor tab style to ensure tabs work as expected
git-gui: correct assignment of work-tree
git-gui: use full dialog width for old name when renaming branch
git-gui: generic version trimming
git-gui: enable the Tk console when tracing/debugging on Windows
git-gui: show command-line errors in a messagebox on Windows
On Windows, avoid git-gui to call Cygwin's nice utility
