parse_pathspec: support prefixing original patterns
This makes 'original' suitable for passing to an external command
because all pathspec magic is left in place, provided that the
external command understands pathspec. The prefixing is needed because
we usually launch a subcommand at worktree's top directory and the
subcommand can no longer calculate the prefix itself.
This slightly affects the original purpose of 'original'
(i.e. reporting). We should report without prefixing. So only turn
this flag on when you know you are about to pass the result straight
away to an external command.
