Merge branch 'da/difftool'
* da/difftool: mergetool--lib: simplify API usage by removing more global variables Fix misspelled mergetool.keepBackup difftool/mergetool: refactor commands to use git-mergetool--lib mergetool: use $( ... ) instead of `backticks` bash completion: add git-difftool difftool: add support for a difftool.prompt config variable difftool: add various git-difftool tests difftool: move 'git-difftool' out of contrib difftool/mergetool: add diffuse as merge and diff tool difftool: add a -y shortcut for --no-prompt difftool: use perl built-ins when testing for msys difftool: remove the backup file feature difftool: remove merge options for opendiff, tkdiff, kdiff3 and xxdiff git-mergetool: add new merge tool TortoiseMerge git-mergetool/difftool: make (g)vimdiff workable under Windows doc/merge-config: list ecmerge as a built-in merge tool
