Kevin may have forgotten a reply all, but he proposed a POSIX compatible fix, rather than relying on undocumented behavior.

I tested out this fix and it works on GNU sed. The -E option is not
documented in GNU sed but it is an alias of the -r extended regular
expressions option. It may be slightly better to use the -r option
instead as it is documented in both implementations (the BSD man page
says it is an alias of -E).

So while this fix works it might be worthwhile to stick posix basic (as
that is what is used throughout pass and since extended is not part of
posix sed (AFAIK). To continue with posix basic the `\?` can be
replaced with `\{0,1\}` which should work on all compliant seds.
