- Allow realpath to accept multiple paths on the command line.
- Add -q to suppress warnings if some paths can't be processed, and use
getopt(3) to process flags.
- Print the path being requested rather than a possibly partially
processed path when a failure occurs so that you can tell which of
several passed paths did fail.

This lets you resolve pathnames to their underlying physical path:
critter# realpath /sys/kern/subr_disk.c
/freebsd/src/sys/kern/subr_disk.c
Update the pwd man-page slightly.
