[prog] Returning a string from a function, in bash

is there a specific reason for explicitly returning 0 and 1, rather
than just writing "return $?".  I would've thought that if you test
for "-ne 0" on the return code afterwards, the net effect would be
the same (at least if there's no other code in between).  Is there
some subtle issue with "return $?" - which, as I understand it, would
sort of assign $? to itself? (serious question, not just wanting to
be clever).

Thanks,

Riccarda
