[PATCH] textproc/glimpse: memcpy -> memmove

[attila]

Hi ports@,

I use glimpse heavily, although I know it's old... I'm used to it, I
guess.  It just dumped core for me under -current and the reason was
memcpy/memmove.

I am attaching a patch that made the core dump go away, and attempting
to submit this patch to the upstream but I thought I would give any
OpenBSD glimpse users a head's up.  It only happens to me when I
search very large indexes.

Pax, -A
