Don't downcase non-ascii identifier chars in multi-byte encodings.
Long-standing code has called tolower() on identifier character bytes
with the high bit set. This is clearly an error and produces junk output
when the encoding is multi-byte. This patch therefore restricts this
activity to cases where there is a character with the high bit set AND
the encoding is single-byte.
There have been numerous gripes about this, most recently from Martin
Schäfer.
Backpatch to all live releases.
