I tried 'dir /X %pathname%', or 'dir /X /B %pathname%' (and other combinations),
i can produce "some" 8.3 strings, bug was unable to produce the replacement
of the full path (with 8.3 strings replaced everywhere). And setting the
result in another variable seems another challenge…

On the other hand, i have discovered something funny to calculate the directory
where a bat file is installed:

pushd %0\..
set dirname=%cd%
popd

This seems to work in all situations (spaces in filenames, bat file called through
absolute path or relative path, even the simple foo.bat works…). It also removes
the annoying quotes that are set around %0.

It's a good trick, did anybody know this?
