Merge commit.
Regex-Tests-Core-ct.15:
Tests #escapeRegex from Regex-Core-ct.61.
Revision: Rename to #escapeForRegex (complements Regex-Core-ct.78).
Regex-Tests-Core-ct.17:
Adds a regression test for parsing regular expressions with nested quantifiers. Thanks to Conrad Halle for reporting this bug!
Regex-Tests-Core-ct.18:
Adds regression test for a bug while parsing lookaround-like regexes.
Regex-Tests-Core-ct.19:
Tests non-capturing groups. Complements Regex-Core-ct.63.
Regex-Tests-Core-ct.20:
Adds regression test for captured lookaround expressions.
Regex-Tests-Core-ct.21:
Adds regression tests for quantifier sequences.
Revision: Extends tests with all possible minimal/possessive quantifiers and explanation.
Regex-Tests-Core-ct.22:
Complements Regex-Core-ct.66 (convenience selectors).
Regex-Tests-Core-ct.23:
Complements Regex-Core-ct.67 (named capturing groups).
Revision: Add updated tests for #keyedSubexpressionRanges: and #subexpressionRanges:.
Regex-Tests-Core-ct.25:
Fixes #testOptionalLookbehind2. It still fails, but this time for the real bug in the matcher instead of a lowercase slip in the test.
Revision for Regex-Core-ct.70 from Regex-Core-ct.78: Fixes #testOptionalLookbehind2 really, resolves the expected failure, and merges it back into #testOptionalLookbehind. Adds #testMatchNullable.
Regex-Tests-Core-ct.26:
Tests nullable closures that are introduced in Regex-Core-ct.70.
Revision: Don't deny nullable lookarounds any longer in #testLookaroundParser.
Regex-Tests-Core-ct.27:
Merges two tests that are no-longer to do.
Regex-Tests-Core-ct.28:
Complements Regex-Core-ct.71 (Unicode backslash atoms). ... Merges Regex-Tests-Core-tobe.17.
Revision: Add test for non-existing Unicode category.
Regex-Tests-Core-ct.30:
Complements Regex-Core-ct.66 (convenience selectors).
Revision: Adds regression fixture on order of capture groups within branches (complements revision in Regex-Core-ct.78).
