The following patch to Xaw/Text.c fixes the bug recently reported by
me about ^L not behaving properly. The problem is that the function
which handles the redisplaying assumes that the insertion point is
currently on-screen when the function is called, and this assumption
is not always valid (of course, it can be argued that THAT is a bug,
but that's another story).
