Fix problem introduced in yesterday's commit that broke both signed and
...
unsigned character machines. So that people don't have to reverse engineer
this again:
mksyntax detects if characters are signed or not and builts a syntax
table that has a base of 129 for signed characters or 1 for unsigned
characters. This is so the largest negative signed char [-128] + the
base == 1. 0 is special and means end of file in both cases. PEOF
is -1 for the unsigned character case and -129 for the signed
character case, so that syntax[PEOF + base] == syntax[0] == CEOF
So PEOF has to be -1, but it is explicitly compared with
unsigned characters on machines where characters are unsigned.
The quick fix is to define UPEOF the (unsigned char) version of PEOF
and use that. A better fix is to always use unsigned characters
when referencing symbol table entries, but that would require
extensive changes to the shell. So to summarize
syntax[0] == CEOF, base + PEOF == 0
unsigned signed
base 1 129
PEOF -1 -129

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.

are honored during and after the execution of the script.

Changed so that syntax errors (EXERROR) set the exit status to 2,

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
foo=bar
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
