Feature #16491: ruby string scan can not support full regex string feature

I have a complex regex string which works fine with match method, but fails with scan. and I think it is because the scan method does not implement full function link match. please see attached test file.

the test match regex is /<testsuites((?!</testsuites>).|\n)+</testsuites>/m

Try this regex:

/<testsuites(?:(?!<\/testsuites>).|\n)+<\/testsuites>/m

String#scan returns an array of whole matched strings if the regex has no capture, but it returns captured strings ($1, $2, ...) if the regex captures them. Your regex uses (...) which is a capture. Instead, you may want to use (?:...) which does not capture a string.
