I found another bug to investigate (don't know if it's related ;-).

Using your test case, I looked to see if I could get valgrind to
show me a problem (no...), and if I could get the 'working' mode
to show that it was related (no...).

But what I did was hold the key down that I was inserting, and just let it
go for a while.  After about 50-60 screens shifted-right, the cursor and
the insert-point stop tracking together (it continues to insert, but the
two move at different rates).  That's about 3kb of inserted text.  But
valgrind doesn't complain, and it's unrelated to 'working'.

However, a quick check shows it doesn't happen in en_US locale - it's
a problem with the en_US.UTF-8 locale.  I'll dig into that...

I've stirred up quite a can of worms here haven't I!  :-)

I suppose so. The one that I did fix was a bug that I'd like to have caught before now (the reason for just focusing on bug-fixes for 9.7).

The other I wouldn't have seen unless I was digging deeper to find
something to reproduce from your report.  (It did seem like a lot of
shift-right's, but I think I counted off 57-58 consistently - it has
to be related to the specific data...)
