Both this and an earlier change in this series replaces a callback
command with an invocation of system() without any error checking. So if
this add-helper fails for whatever reason we'll silently fail to report
it.
I think it makes sense to put something like the following WIP code
earlier in the series. Then if the command was e.g. ["false", "git",
"status"] we'd see:
What now> s
oh noes when running 'false git status': returned error '1'
WIP patch. Obviously not ready as-is, but feel free to consider this to
have my SOB & adapt it.
