small elaboration in tips.texi

[Ken Manheimer]

i hadn't connected the fact that requiring a package for macros can be
limited to the byte-compilation phase, since the macro expansions are
compiled in to the resulting byte-code.  i've elaborated the entry

i'm including the patch inline below my signature.
