Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add string -> number conversion for preproc expression evaluator Q&D conversion from string to signed number. It should be noted that this really should be done during tokenization and the type of number be set by the tokenizer, including parsing floating point values. Then the preprocessor can decide what to do with non-integer numbers.
