nested capture groups

[charlierudolph]

Currently having a nested capture group regexp throws an error in the javascript version (see cucumber/cucumber-js#825)

// Two capture groups. The outer one should typically be non-capturing but doesn't need to be
/^a user( named "([^"]*)")?$/

// Workaround is to make the outer on non-capturing
/^a user(?: named "([^"]*)")?$/

I would suggest just throwing an error if there is a nested capture group and suggesting making the outer one non-capturing. Thoughts?

The same error can be run into when defining a parameter type where the regexp contains a capture group.

Yeah throwing an error with an explanation sounds like a good idea.

Fixed by #227 - we're not throwing an error, just passing null instead.
