The bash behaviour makes it impossible to call shell functions
that invoke getopts while in the middle of an getopts loop.

IMHO the dash behaviour makes a lot more sense since a function
always brings with it a new set of parameters.  That plus the
fact that this behaviour has been there since day one makes me
reluctant to change it since the POSIX wording is not all that
clear.
