commit af7b0f4a468cee55ba2500b6373af2ee63d3bf45
Author: G. Branden Robinson <g.branden.robin...@gmail.com>

src/roff/troff/input.h: Add macro dump lookup aid.
Add comments corresponding to JSON-encoded representations of C0 and C1
control code points that GNU troff uses its document/formatter debugging
features, and which are needed for forthcoming `pm` macro/string/
iversion dumping support. (And existing device extension command
dumping support, when something naughty gets into one.)
This isn't as good as decoding them in the dump output, but their
embedding in JSON string objects makes a good means of doing so
non-obvious to me.
