annotate src/bufslots.h @ 5247:02d875ebd1ea
Make Lisp reader errors more informative with over-long hex, octal characters
src/ChangeLog addition:
2010-08-21 Aidan Kehoe <kehoea@parhasard.net>
* lread.c (read_escape):
Make error messages better reflect the text that was encountered,
when overlong hex character escapes or non-Latin-1 octal character
escapes are encountered.
man/ChangeLog addition:
2010-08-21 Aidan Kehoe <kehoea@parhasard.net>
* lispref/objects.texi (Character Type):
Go into more detail here on the specific type of error provoked on
overlong hex character escapes and non-Latin-1 octal character
escapes; give details of why the latter may be encountered, and
what to do with such code.
