annotate tests/automated/query-coding-tests.el @ 4596:4fc32a3a086e

Fix a couple of bugs, #'query-coding-region, #'query-coding-string. 2009-02-04 Aidan Kehoe <kehoea@parhasard.net> * coding.el (query-coding-region): Revert this to being a defun, add a compiler macro without needless binding. (query-coding-string): Correct a bug here, string indices are zero- not one-based. * mule/general-late.el (unicode-query-coding-skip-chars-arg): Correct the algorithm used to initialise this variable.
