the file has been reworked in commits

now the code is entirely different and works as expected.

IIRC when I worked on this piece of code, _guix_is_command "foobar" was
looking for foobar in all words of the command. So you could have
_guix_is_command returning true for "build" and "system" at the same
time when using "guix system build".
