This is a scan of mistakes in regexp strings in the Emacs source tree.

New this time, in addition to general improvements to the regexp finder and partial evaluator, is support for parsing and linting arguments to `skip-char-forward' and `skip-char-backward'. This turned out to be quite fruitful, since the syntax of skip-set strings is widely misunderstood.

The scan was made using trawl 1.3 (https://github.com/mattiase/trawl) and xr 1.8 (ELPA).

Please help fixing these. In particular, someone who knows Hebrew would be of assistance.
