The longer I read your explanation, the less useful the "PC mode"
sounds like, at least to me. So why does an user even want to use
such a mechanism, instead of PS1? And even if the user wants to use
it by doing \w, \u etc. himself, she can do that with
PROMPT_COMMAND='
PS1=$(printf "\u \h \w %s$ " $(__git_ps1 "%s"))
'
just fine, no?
So I still do not see the problem, even taking your "Set PS1 in the
command, without spitting anything out of the command" use case into
account.
Confused....
