Out of curiosity, how exactly is that used ? I have a hard time coming
up with an example where I would want to glob by character set.

globtolike goes to show that hours of hacking can easily save you 5
minutes of reading docs. Turns out that sqlite has a (non-ANSI) operator
'glob' which does exactly what is needed here. Updated patch attached; I
can now successfully run 'yum install [xyz]p?f*'.

BTW, packages.parsePackages checks if the pattern contains '[\*,\[,\],
\{,\},\?]' - I think the '{}' shouldn't be in there, they are not
special in globs, and fnmatch.translate just puts them literally into
the regexp.
