Subject: foo-x.y vs. foo-part-u.v

We currently have the problem with meta-style packages that collect
several packages under one name (nethack comes to mind, several others
exist), that we can't call the meta-style-package just foo-x.y, as the
magic in will recognize any installed foo-part-u.v as an old
version of foo-x.y (by just looking for foo-*), and stopping installion.

The '*' in the foo-* should only match the version number of any installed
foo-packages, but instead it happily matches any foo-part packages as
well. That's annoying, and we have worked around this by naming them
foo-all-x.y, but this is not a nice solution.

I've had a closer look at our version numbers, and as we can't do an
eqivalent of the regular expression '[^-]+' in shell globs, and ALL our
version numbers begin with a digit, I'd suggest that we don't look for
foo-* to find any "old" versions, but for foo-[0-9]* instead. 

A patch for this is attached below. 

Any objections to apply it?
