i believe Ruda's solution comes very close: pipe selected range to separate
window (+Error, if you must) and then operate on it. However, it is not good
enough: line numbers do not match original file.

Is there a way to recover range of dot from script ran from Acme window? I
couldn't find; expected the `acme/$winid/addr' file to contain char ranges of
dot after `echo addr=dot | 9p write acme/$winid/ctl', but the
`acme/$winid/addr' stays `0 0'. Using plan9port here.

If there was a way to get $firstLine, $lastLine or $firstChar, $lastChar, it'd
be easy enough to filter lines with sed or awk for match of both RegEx and line
number or char range. Or to re-number lines as output by grep.
