[PATCH] lei: show searches prefixed with `.'

[Eric Wong <e@80x24.org>]

Sometimes, a user will use an output with a basename which
starts with a `.'.  glob("*") won't list files prefixed with `.'
by default and glob(".* *") requires iterating twice on my
system.  So just rely on Perl regexps instead of glob to get the
directory listing done in a single pass.   We can improve error
detection with autodie for opendir, as well.
