Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
When locale is enabled, sprintf("%.123s", str) is counting characters, not bytes, so we can't globally enable locale without opening stack/heap smashing vulnerabilities. Make commands individually request setlocale() using TOYFLAGS instead.
