util: raise ParseError when parsing dates (BC) a7dce526c462 refactored util.parsedate in order to raise ValueError instead of Abort for using with ui.configwith. It causes several problems, putting arbitrary bytes in ValueError can cause issues with Python 3. Moreover, we added a function to convert ValueError exceptions back to Abort. A better approach would be to make parsedate raises ParseError, removing the convert function and update configwith to also catch ParseError. The side-effect is that error message when giving an invalid date in CLI change from: abort: invalid date: 'foo bar' to: hg: parse error: invalid date: 'foo bar' I'm not sure if it's an acceptable change, I found personally the error message more clear but more verbose too.
