Because "more is less", both executables are generated from
the same source code. In fact, those are the same binary,
hardlinked.

% which more less | xargs ls -l
-r-xr-xr-x  2 root  wheel  118788 Aug 21  2011 /usr/bin/less
-r-xr-xr-x  2 root  wheel  118788 Aug 21  2011 /usr/bin/more

So there is no separate source code for "more". Similarly,
zless, bzless, xzless, and lzless are "created". They're
all the same shell script, refering to /usr/bin/less.

They don't. :-)

Make sure the hardlinks are created correctly. You can do that
with the "make install" command in the system's source tree
after applying your patch. See /usr/src/usr.bin/less/Makefile
for details.

Change the source code directly in the proper /usr/src subdirectory
or create a patch with a work copy. Then install it.

As briefly explained. :-)
