Nearly. The options combine now, but builtins don't take precedence. As
explained above, I'd expect "command -pv echo" to output simply "echo"
and not "/bin/echo", because it's a builtin. Also 'command -pv :' should
output ':'.
Ref.:
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/command.html#tag_20_22
(note: the wordage under -p, "Perform the command search using a default
value for PATH [...]", does not mean "make it a path search even if
there's a matching builtin"; it just means "ignore $PATH and use the
system default path instead, if applicable".)
Thanks,
