If reg.exe is not there kdiff3 will not be found. The code will
already be _ignored_. It's just not working.

It may make sense to use 'uname -s' to explicitly control that the
code is expected to work. This would allow to report errors if a
command is missing. However, cluttering all shell scripts with
uname's will likely become quite confusing.

If performance is a concern, we may execute uname -s only once
in git-sh-setup and assign its return to something like GIT_UNAME.
This may save us a few forks, which are to my knowledge quite
expensive on Windows.
