comparison Python/pythonrun.c @ 6661:99955b65408d legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Apply str() to sys.ps1 or sys.ps2 before using them as a prompt, so you can assign an object whose str() evaluates to the current directory (or whatever).
