CVS commit: src/usr.bin/unexpand

Module Name:    src

Modified Files:
        src/usr.bin/unexpand: unexpand.c

Log Message:
Fix a handful of bugs in unexpand(1):

1. -a and -t were mutually exclusive when they should not be.

2. `unexpand -t n` did not treat a file like there were stops at n, 2
   n, 3 n, 4 n, and so on.  So expanded tabs after column 4 were not
   collapsed.

3. a debug fprintf wrote every tabstop set with `-t` to the standard
   error stream.

TBD write some tests.
