If stdout is a tty, use vis(3) to print any filenames to prevent garbage
from being printed if the filename contains control- or other non-printable
characters.
While here, sprinkle some EXIT_FAILURE and NOTREACHED where appropriate.

Return ENOENT instead. Closes PR 6975 by Johan Danielsson <joda@pdc.kth.se>.
From FreeBSD: return correct error message if source directory is
unreadable; remove unnecessarily included headers.
It's suppsed to remove the file and then copy, which it wasn't doing.
But no wait, it turns out that the described behaviour in the manual doesn't
agree with POSIX. So we change the above fix and the manual to "try copy, and
if fail, try remove, then copy".
Fix bug where "cp -R" didn't work on read-only directories:
It would make the directory, set the mode, and not be able to write files into it.
Don't bother mmap()ing files of zero length. Was a workaround for a bug in Rhapsody
mmap(), which didn't get along with such files, but makes sense anyway.
Fix race condition where "cp -p" would set the mod time of a file before close()ing
the file, which would update the mod time and therefore screw up the "-p" idea,
except, of course, while running in gdb, which sucked.
Add -f option to usage message in binary and man page. Already documented in man page.

very bad if it is actually a device or fifo. POSIX.2 requires that a
diagnostic message be written, the file descriptor be closed, and for
cp to continue on with the rest of the files.

A utility is a executable, script or shell builtin; while a command
can be any of those things plus lists, pipelines, compound commands
(if, for, while) and shell function definitions.
