annotate src/debug.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.
