I noticed this when checking out the n0qorg, being outside a git repository would have an undecorated
detached:
(fromSCM_THEME_DETACHED_PREFIX
) in the prompt. It's easy enough to correct this in the theme but since the problem also may be observed in hawaii50, iterate, pro, standard and zitron as well, andgit rev-parse
is fast to execute anyway, this seems to be the correct place to insert this quick check.
