[PATCH 3/4] _command_name: Check for external forcing precommand

[Matthew Martin <phy1729@gmail.com>]

Do not complete internal "commandish" possibilities if there is
a precommand that forces an external command. This means each caller of
_normal (that uses -p or next patch -P) need not split out the command
word (cf. _setsid and _command).

Move builtin_precommands into _main_complete where precommands is made
local, so the definition need not be duplicated in _pick_variant and
_command_names.
