Michael Forney 6164445cce Fix symbolic mode parsing in parsemode 
I found quite a lot of bugs, so I ended up pretty much rewriting as I
followed the spec¹.

Now, it works as follows:

- Determine a mask (who) of bits that can be modified for the subsequent
  operations. If none are specified, select all file mode bits.
- In a loop, determine which operation (+, -, =) to apply.
- If the next character is a permcopy (u, g, o), set the new permissions
  (perm) corresponding to the bits set in the user, group or other parts
  of the existing mode.
- Otherwise, set the new permissions by looping through the next r, w,
  x, s, t characters.
- Now, the set of bits we want to add or remove is (who & perm). Set or
  remove these bits according the the operation (first clearing the
  appropriate bits if the operation is =).
- Continue from the top if the next character is a comma, otherwise,
  process the next operation.

I tested this on some made up inputs, and I believe it is working
correctly now:

  parsemode("g+w", 0644, 0),    before: 0606, now: 0664, fixed
  parsemode("u+rx", 0222, 0),   before: 0077, now: 0722, fixed
  parsemode("+x", 0644, 023),   before: 0754, now: 0754, still works
  parsemode("+w", 0444, 022),   before: 0644, now: 0644, still works
  parsemode("+w", 0444, 0),     before: 0666, now: 0666, still works
  parsemode("+s", 0755, 0),     before: 0755, now: 6755, fixed
  parsemode("u+s", 0755, 0),    before: 0055, now: 4755, fixed
  parsemode("g+s", 0755, 0),    before: 0705, now: 2755, fixed
  parsemode("g=u", 0700, 0),    before: 0000, now: 0770, fixed
  parsemode("go=u-w", 0700, 0), before: 0000, now: 0755, fixed
  parsemode("o+u-g", 0641, 0),  before: 0000, now: 0643, fixed
  parsemode("u=rx,o+w,g-r", 0654, 0) before: error, now: 0516, fixed
  parsemode(",", 0654, 0), before: error, now: error, still works

sin ff93350289 Fix col(1) -f 
patch taken from openbsd.

Ingo Schwarze says:

If you call the col(1) utility with the -f option, permitting forward
half-line feeds in the output stream, and the input stream actually
contains half-line feeds in either direction, you end up with corrupt
output, containing meaningless escape-digitnine sequences instead of
the required escape-tab sequences.

   $ hexdump -C half.txt
  00000000  61 1b 09 62 1b 09 63 0a                    |a..b..c.|
  00000008
   $ col -f < half.txt | hexdump -C
  00000000  61 1b 39 0d 20 62 1b 39  0d 20 20 63 0a    |a.9. b.9.  c.|
  0000000d

Note how the third character changes from 0x09 to 0x39.

OK to commit the following fix?  Don't worry, it isn't dangerous,
it only changes two *bits*, only a quarter of a byte.

The bug was introduced by the original author, Michael Rendell,
and committed by Keith Bostic on May 22, 1990 (SCCS rev. 5.1).

The following operating systems are affected:

 * 4.3BSD Reno, BSD Net/2, 4.4BSD, 4.4BSD Lite1, 4.4BSD Lite2
 * All versions of 386BSD, NetBSD, OpenBSD, FreeBSD and DragonFly
 * All versions of Debian GNU/Linux and probably many other Linuxes

sin 8311023781 Fix test(1) semantics 
Evan Gates says:

After writing my own test[0] I checked and sbase already has test. I'm
including a patch to remove test from the TODO. I also noticed that
sbase's test handles a few specific cases incorrectly (documentation
at [1]).

test ! = foo
When there are 3 arguments and the second is a valid binary primary
test should perform that binary test. Only if the second argument is
not a valid binary primary and the first is ! should test negate the
two argument test. I've attached a patch that should fix this.

test ! ! !
test ! ! ! !
When there are 3 arguments and the second is not a valid primary and
the first is !, test should return the negation of the remaining two
argument test. In this case sbase's test works correctly for ! and ! !
but fails afterwards as it's not recursive. I don't yet have a patch
for this but I'm working on one.

Then again both of these areas may be places in which worse is better.
