This should not affect use of -p with yes(1) [as every locale I know of matches
'y' as YESEXPR as well], but that's what -t is for anyway. -p is meant to be
really used interactively.

out the parse loop to a seperate function, and move local variables around as
is needed. To keep the state of some variables and keep from having huge arg
lists to functions, make a bunch global.
Change use of err(3) in situations where malloc(3) will be setting errno to
errx(3) since assuming malloc(3) sets errno is non-portable, and provides no
more useful information in the context of FreeBSD.

Update strnsubst to have one or two extra conditions which maybe would make

Merge xargs(1) with that of xMach.
Bring in xargs(1) changes to add -L and -I as per the Single Unix Specification
version 3. Proper exit status numbers are implemented, and the manual page has
been updated to reflect reality.
The code has been ANSIfied, and a new file has been added to xargs(1) to do the
substring substitution as SUSv3 requires.
Traditional behaviour should not be affected, use of -J should be deprecated
in favor of the more portable -I (though -J has been left, for now).
