Yes. Unfortunately, I just noticed that it will also match *zero*
characters in that position (since the ‘*’ matches zero or more of the
preceding atom). This contradicts the common wisdom to make the regex
as specific as possible.

So, a better example would be:

    ftp://ftp.tex.ac.uk/tex-archive/web/c_cpp/cweb/cweb-(.+)\.tar\.gz

which will match only when there are one or more characters in the
version-string position.
