Rather than writing a separate ending, I'd like to just parenthesize
the last three chords over the final two bars so they would render:
F ( Ab7 Dbmaj7 C7 )
ChordName outputs via text-interface, so the easiest way should be
\once \override ChordNames.ChordName #'text = "("
But this has no effect. It probably acts too early,
i.e. before the Chord_name_engraver has written its result to #'text.
Trevor answered a similar question a year ago:
http://lists.gnu.org/archive/html/lilypond-user/2008-03/msg00275.html
His solution modified the stencil, letting it overwrite #'text
just before printing.
As "addBrackets" it wrapped only a single chord, but you could
derive a left_only and a right_only version easily enough.
But if you want the bracket standing alone, how about setting up
a superfluous chord at the right place, and overwritung that?
See the snippet below; overwriteCN could also do things like "N.C."
Cheers,
Robin
