There appears to be an easy bug in iso9660 helper:
if (name ~ /^\.\.?/) next
means "skip all lines which start with one or two dots".
Author probably meant: if (name ~ /^\.\.?$/) next
I propose to not be cryptic and just check both possibilities separately.
The below trivial patch was tested to work: now I see
the file named ".dot" in a test iso file.
(Note: there seems to be another bug: SEMICOLON = "YES"
is not a correct comparison (should use ==),
it's assignment! As a result, sub(";1$", "", name);
is always executed).
