Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Core: fixed segfault with null in wildcard hash names. A configuration like server { server_name .foo^@; } server { server_name .foo; } resulted in a segmentation fault during construction of server names hash. Reported by Markus Linnala. Found with afl-fuzz.
