I guess we could introduce a function that does some form of
post-processing , if a style is set. Valid settings could be "quote" or
"strip" and "function", the latter would dispatch to a named function,
for example for the user to get full control. That function could be
used everywhere where a string from an external program is used.

That way, prompt_subst users (if you don't use prompt_subst, which is
the default, none of this is an issue) can get post-processing if they
like. Actually, we could make the default depend on the state of the
option when vcs_info initialises.

Unfortunately, I can't look into it right now due to lack of spare time.
