Joerg Wunsch e3fa32b485 Implementing the "lp" command.
This command is required to exist in terms of compatibility with the
Posix 1003.2 specification.  It actually invokes the lpr service with
the proper options.

# XXX Bugs:
# . Our lpr command is not smart enough about dashes as input file names,
# they should indicate the use of standard input.
# . Our /bin/sh is not Posix-1003.2 compliant in its getopts command;
# if the user specifies an option argument immediately after the
# option, the variable OPTIND will be set wrong. (This way of
# specifying option arguments is deprecated by Posix, but explicitly
# allowed.)
# . Our lpr command should allow the Posix-compliant way of specifying
# options that take an argument; it currently requires the argument
# to follow the option immediately.
