This came in in mid-2015 as part of a set of fixes to `command -p'. I think
the bash-4.4 and later behavior is correct: just because you're telling
command to use a standard path it doesn't mean it should not act like it
would in any other circumstance. There's nothing in POSIX that contradicts
that.
