getopts fixes:
...
1. OPTIND value was not computed correctly when the argument was part of the
option string (i.e. for "l:" "-l 1" was working "-l1" was not). (PR/2505).
2. OPTARG was not being unset in case of errors [in the non POSIX error case].
3. optvar could be set to random values.
4. Option string starting with a : was not treated specially as POSIX
specifies (if the option string starts with a :, then there is no
error printed when there are missing option arguments or illegal options,
and OPTARG and optvar are being set specially).
5. Implemented getopts "opts" optvar [arg]. The optional argument case
was not implemented.
To do:
- what does Posix say about resetting the getopts state? Bash does it
by setting OPTIND=0; is that correct? Should we be doing the same thing?
- should we be using getopt(3) for everything internal to the shell? Is that
feasible because we might need to handle multiple invocations at once.

and commands that are not found set the exit status to 1 like all
other bourne shells.
[It used to be 0 and 2 respectively]

Fixed new bug the previous fix introduced:

false

echo $?
would print 1
Also fixed the long standing bug:
false
echo `echo $?`
would print 0
The exitstatus needs rethinking and rewriting. The trial and error method
is not very efficient
