Add escaping to quoted strings, differentiate between literal and regular strings. The goal is to make string processing in config files as close as possible to toml standards. This means handing escape sequences including unicode, and differentiating between literal strings and regular strings in files and when splitting the command line. Also allowing variable names in the files to be quoted. This PR gets partway there. Removes some hacks from the previous PR to deal with unusual option names and replaces with the quoted names. --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com>
