lynx-dev INSTALLATION file changes (was: Fix --disable-trace, #includes)

[Klaus Weide]

I agree that the new text is mostly better.  (Removing *.old stuff is
a different topic).  But:

That last sentence reads as if editing userdefs.h was completely unnecessary
and not recommended at all if configure is used.  That's of course not true.
There are only a handful of userdefs.h settings that can be preempted with
flags to ./configure.

It also contradicts what userdefs.h says.   More than two thirds of it are
in sections marked "MUST change (or verify)".  [In practice, that MUST isn't
true for most users since there are sensible defaults, and I doubt many
people take it seriously.  But some options that really need to be reviewed
by the installer (like GLOBAL_MAILCAP) are grouped together in section 1.)
with others that can be safely left at their defaults (like GOTOBUFFER).
The latter really don't deserve to be marked as "MUST change".  That's
probably all or most of current 1c).]

Henry didn't change it, but I noticed that Step 3 is giving wrong advice;
it would be more correct with the 5 words inserted below.
