git-difftool worked for me on an up-to-date Gentoo Linux at home, but
didn't work on a somewhat older Ubuntu Linux 7.10 at work and failed
with the following error, where 'Makefile' was locally modified:
trap: 244: SIGINT: bad trap
external diff died, stopping at Makefile.
In 'man 1p trap' there is written:
"The condition can be EXIT, 0 (equivalent to EXIT), or a signal
specified using a symbolic name, without the SIG prefix, [...]"
"Implementations may permit names with the SIG prefix or ignore case
in signal names as an extension."
So now we do it the POSIX compliant way instead of using an extension.

You only need to edit worktree files when comparing against
the worktree. Put the cursor automatically into its window for
vimdiff and gvimdiff to avoid doing <C-w>l every time.

'git difftool' is a git command that allows you to compare and edit files
between revisions using common merge tools. 'git difftool' does what
'git mergetool' does but its use is for non-merge situations such as
when preparing commits or comparing changes against the index.
It uses the same configuration variables as 'git mergetool' and
provides the same command-line interface as 'git diff'.
