Title: Do not hang on `colordiff --help` which breaks bash auto-completion

Recognize that `--help`, `--version` and `-v` are options for `diff` and therefore do not act as a filter.

In addition, fix a bug that would eat `-v` and options like `-d` due to the auto_abbrev feature of Perls Getopt library.

This fixes a regression introduced with version 1.0.10.
