Some changes seem to be just different personal preferences,
is that right?

For example I just ran across this in LYForms.c:

#ifdef SH_EX
/* ASATAKU emacskey hack 1997/08/26 (Tue) 09:19:23 */
        if (emacs_keys &&
            (EditBinding(ch) == LYE_FORWW || EditBinding(ch) == LYE_BACKW))
            goto breakfor;
/* ASATAKU emacskey hack */

(Quite old change date)

I do not know whether that is is personal customization or whether it
is meant as a general improvement / bug fix.  If it's the second,
then it should get un-ifdef'd.

It caused memory leaks.  See

also Tom's summary in CHANGES:

* undo spurious change from win32 integration in dev.5 to HTSprint0() which
  causes a memory leak (reported by John Bley, analysis KW) -TD

If something bad happens because of that change, then something must
have used HTSprintf0 the wrong way.  That code should be fixed.

(I did not understand the description "a movement was unstable".)
