From: Charles Bailey <cbailey32@xxxxxxxxxxxxx>
git-difftool used to create a command list script containing $( ... )
and explicitly call "sh -c" with this list.
Instead, allow mergetool --tool-help to take a mode parameter and call
mergetool directly to invoke the show_tool_help function. This mode
parameter is intented for use solely by difftool.

Another issue for Solaris. Originally I had a fix for this that
substituted "@SHELL_PATH@" even inside perl scripts but I felt that
having an interface for show_tool_help was a little neater all round but
I welcome alternative views.
