Linus TorvaldsI had meant to disallow unknown escape characters in the config file parser, but instead an unknown escaped character would silently pass through as itself. That's correct for some cases (notably '\' itself), but wasn't correct in general.
This fixes it, and makes the parser write a nice error message if the config file contains bogus escaped characters.
