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.

BTW, there is no public repository for GNU ed. Patches are a rare occurrence 
here.

Best regards,
Antonio.
