File size: 60174 byte(s)
Tidy up, remove trailing spaces, etc. for 8.00-RC1.

1 /-- 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 either because PCRE can't be compatible, or there is potential Perl
6 bug. --/
7
8 /-- Originally, the Perl 5.10 things were in here too, but now I have separated
9 many (most?) of them out into test 11. However, there may still be some
10 that were overlooked. --/
