replace: deal with overlapping.
* buf.c (replace_buf): In the same-type case, use memmove
rather than memcpy in case the objects overlap, so we
don't invoke C undefined behavior.
* lib.c (replace_str, replace_vec): Likewise.
* txr.1: Specify that if the replacement sequence overlaps
with the target range of the destination sequence, or
with any portion that has to be relocated if range
changes size, then the behavior is unspecified.
