Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Avoid clearing print-gensym-alist inappropriately when printing hash tables. 2008-01-15 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el (thing): Check that printing a hash table literal doesn't clear print-gensym-alist. 2008-01-15 Aidan Kehoe <kehoea@parhasard.net> * print.c (prin1_to_string): New. The guts of Fprin1_to_string, without resetting Vprint_gensym_alist. (Fprin1_to_string): Call prin1_to_string, wrapped with RESET_PRINT_GENSYM calls. * doprnt.c (emacs_doprnt_1): Call prin1_to_string, not Fprin1_to_string (dos veces). Avoids an inappropriate reset of print-gensym-alist.
