Thank you for the patch. POSIX states[1] that "The ed utility shall support basic regular expressions, as described in XBD Basic Regular Expressions", but yours looks like a nice extension that could be even eventually standardized by POSIX. I'll implement it ASAP and will publish a new release.

Best regards, Antonio.
