Offhand, I don't, and the docstrings/source comments are less than 100% reliable. Anyway, I've implemented a last-match-succeeded flag (for debug usage only) and check it in match_limits and Fmatch_data (when XEmacs is configured for error-checking). If we catch anything that looks relevant to GNU Emacs I'll report it here. -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
