From: John Keeping <john@xxxxxxxxxxxxx>
The "--tool-help" option to git-difftool currently displays incorrect
output since it uses the names of the files in
"$GIT_EXEC_PATH/mergetools/" rather than the list of command names in
git-mergetool--lib.
Fix this by simply delegating the "--tool-help" argument to the
show_tool_help function in git-mergetool--lib.
