find:

	docs don't mention "-xdev" option

grep:

	all kinds of inconsistency here.

	grep [-ihHnqvs] PATTERN [FILEs...]

	Options:


        -H      prefix output lines with filename where match was found
        -h      suppress the prefixing filename on output
        -i      ignore case distinctions
        -l      list names of files that match
        -n      print line number with output lines
        -q      be quiet. Returns 0 if result was found, 1 otherwise
        -v      select non-matching lines
        -s      suppress file open/read error messages

  note how the synopsis doesn't mention "-l".  but notice the line from
  the source file grep.c:

	#define GREP_OPTS "lnqvscFiHhe:f:"

  seems to be several undocumented options: -e, -f, -F, etc.

xargs:

	-p      Prompt the user about whether to run each command
        -r      Do not run command for empty readed lines
        -x      Exit if the size is exceeded
        -0      Input filenames are terminated by a null character
        -t      Print the command line on stderr before executing it.

 however, from xargs.c:

	"Usage: %s [-p] [-r] [-t] -[x] [-n max_arg] [-s max_chars]

  no mention of "-O", but definitely a "-n" and "-s" not documented.
