pr: fix parsing of empty arguments

Before:
  $ pr --expand-tabs=
  pr: '-e' extra characters or invalid number in the argument:
   ‘SHELL=/bin/bash’: Value too large for defined data type

After:
  $ pr --expand-tabs=
  pr: '-e': Invalid argument: ‘’

* src/pr.c (getoptarg): Ensure we don't parse beyond the
end of an empty argument, thus outputting arbitrary stack
info in subsequent error messages.
