Additional atomic group tests.
1 ph10 450 /-- This set of tests is not Perl-compatible. It checks on special features
2     of PCRE's API, error diagnostics, and the compiled code of some patterns.
3     It also checks the non-Perl syntax the PCRE supports (Python, .NET,
4     Oniguruma). Finally, there are some tests where PCRE and Perl differ,
5 ph10 513 either because PCRE can't be compatible, or there is a possible Perl
6 ph10 450 bug. --/
7    
8 ph10 559 /-- Originally, the Perl >= 5.10 things were in here too, but now I have
9 ph10 513 separated many (most?) of them out into test 11. However, there may still
10     be some that were overlooked. --/
