Subject: [PATCH] isofs fix: do not skip all .dotfiles

There is a simple bug in iso9660 helper:

    if (name ~ /^\.\.?/) next

means "skip all lines which start with one or two dots".
Author probably meant:

    if (name ~ /^\.\.?$/) next

I propose to not be cryptic and just check both possibilities separately.

The below trivial patch was tested to work: now I see
the file named ".dot" in a test iso file.
