Ruby: Quotes inside regex literals cause incorrect code parsing

ruby sourcecode with the unrecognized comments

The output of ohcount -a

I can confirm the bug. It applies to any Ruby file that includes quote characters inside of regular expression literals.

Try this:

/'/
# This should be a comment

The unmatched quote inside the regular expression leads the parser to interpret the entire remainder of the file as part of an unterminated string.

The parser requires a new kind of string delimiter, treating / as a string delimiter, similar to ' or ".

'/' cannot always be treated as a string delimiter since it could be used for divisions too, so that there needs to be some code that detects regular expressions and treats only those as string, but mathematical operation shouldn't be treated as strings.

The ruby parser has been considerably improved in the Ragel branch. The sample above now parses correctly.

Although not perfect, the parser is improved enough to close this bug.
