annotate src/debug.h @ 4570:e6a7054a9c30

Add check-coding-systems-region, test it and others, fix some bugs. tests/ChangeLog addition: 2008-12-28 Aidan Kehoe <kehoea@parhasard.net> * automated/query-coding-tests.el: Add tests for #'unencodable-char-position, #'check-coding-systems-region, #'encode-coding-char. Remove some debugging statements. lisp/ChangeLog addition: 2008-12-28 Aidan Kehoe <kehoea@parhasard.net> * coding.el (query-coding-region): (query-coding-string): Make these defsubsts, they're short enough and they're called explicitly rarely enough that it make some sense. The alternative would be compiler macros that avoid the binding of the arguments. (unencodable-char-position): Document where the docstring and API are from. Correct a special case for zero--check-argument-type returns nil when it succeeds, we can't usefully chain its result in an and here. (check-coding-systems-region): New. API taken from GNU; docstring and implementation are independent. (encode-coding-char): Add an optional third argument, as used by recent GNU. Document the origen of the docstring. (default-query-coding-region): Add a short docstring to the non-Mule implementation of this function. * unicode.el: Don't set the query-coding-function property for unicode coding systems if we're on non-mule. Unintern unicode-query-coding-region, unicode-query-coding-skip-chars-arg in the same context.
