Unfortunately (as I expected) the previous change broke:
...
sleep
cmd='set `type "sleep"`; eval echo \$$#'
which=`eval $cmd`
echo $which
because the region did not get recorded at all, and it was interpreted as
a single word. I modified the code to keep track when the result of a
backquote expansion has been recorded to avoid recording it twice. I still
feel that this is not the right fix... More to come.

because when the arquments are not quoted, the backquote result
gets recorded twice. The fix right now is to comment out the
record_region() call in expbackq(). I hope that it does not break
anything else.

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.

Fix return builtin to work like it does in ksh:
...
When not in a function, it skips the rest of the current input file.
Instances of `return' outside function definitions were previously ignored.

Ignore result of sigaction when setting traps. Traps will succeed even

on SIGKILL or SIGSTOP. This is what other bourne shells do. (suggested

Avoid trapping SIGKILL. Pretend that we did, so that we will not keep

other bourne shells.

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
