char *strcat(), *strcpy(), *fgets();

[Joe Keane]

To be useful, strcpy and strcat should return the end of the new
string.  The old method is this:
	(void) strcpy (base, "foo");
	(void) strcat (base, "bar");
	(void) strcat (base, "baz");
This can be replaced by:
	end = strcpy (base, "foo");
	end = strcpy (end, "bar");
	(void) strcpy (end, "baz");
or more concisely:
	(void) strcpy (strcpy (strcpy (base, "foo"), "bar"), "baz");

If you're concatenating many strings, remember this is linear while
the old method is quadratic.  Unfortunately, there's no chance of
getting this changed.  I already have a function like this, i just
don't call it strcpy.
