so litter the code with comments so some other poor soul can come along some
day and work on this if they see fit to do so. Avoid calling strlen(3) to
check for a nil-string, when we can just check for *str=='\0'.

Some people happen to think it's idiotic to limit to 5 arguments, so

code that looks like it was bogus or incomplete.
Update strnsubst to have one or two extra conditions which maybe would make
it more efficient, or at least more versatile. This is likely a no-op.
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).

Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

This fix only removes the dependency on compile time constants. The code
has other (old) problems that need to be addressed.
