annotate src/device.h @ 5785:7343a186a475
Correct some partial character accounting, buffered_bytecount_to_charcount().
src/ChangeLog addition:
2014-01-23 Aidan Kehoe <kehoea@parhasard.net>
* lstream.c (Lstream_read_1):
Don't include the unread partial character in
unget_character_count, since our consumers will never be aware of it.
* text.c:
* text.c (buffered_bytecount_to_charcount):
A buffer consisting entirely of a partial character needs to be
treated as a partial last character, not a partial first
character, to avoid double-counting.
