I for one would rather use the first.  I know about the
spawn* functions but ...

Bingo.  I'll add the above to my toolbox.  Even then I'll
need to figure out which of

os.spawnl    os.spawnlp   os.spawnv    os.spawnvp
os.spawnle   os.spawnlpe  os.spawnve   os.spawnvpe

to use.  Yes I know there's a mnemonic (p = path, e =
environment, v = something, l = something else) but I
forget them.
