9. Fix two occurrences of "backslash" in comments that should have been |

"backspace". |

10. Remove two redundant lines of code that can never be obeyed (their function |
| 46 |
|
was moved elsewhere). |

11. The program that makes PCRE's Unicode character property table had a bug |
| 49 |
|
which caused it to generate incorrect table entries for sequences of |
| 50 |
|
characters that have the same character type, but are in different scripts. |
| 51 |
|
It amalgamated them into a single range, with the script of the first of |
| 52 |
|
them. In other words, some characters were in the wrong script. There were |
| 53 |
|
thirteen such cases, affecting characters in the following ranges: |
| 54 |
|
|
| 55 |
|
U+002b0 - U+002c1 |
| 56 |
|
U+0060c - U+0060d |

|
U+0061e - U+00612 |

U+0064b - U+0065e |

U+01800 - U+01805 |

U+01d00 - U+01d77 |

U+01d9b - U+01dbf |

U+0200b - U+0200f |

12. The -o option (show only the matching part of a line) for pcregrep was not |
| 70 |
|
compatible with GNU grep in that, if there was more than one match in a |
| 71 |
|
line, it showed only the first of them. It now behaves in the same way as |
| 72 |
|
GNU grep. |
| 73 |
|
|
| 74 |
|
13. If the -o and -v options were combined for pcregrep, it printed a blank |
| 75 |
|
line for every non-matching line. GNU grep prints nothing, and pcregrep now |
| 76 |
|
does the same. The return code can be used to tell if there were any |
| 77 |
|
non-matching lines. |
| 78 |
|
|
| 79 |
|
14. The pattern (?=something)(?R) was not being diagnosed as a potentially |
| 80 |
|
infinitely looping recursion. The bug was that positive lookaheads were not |
| 81 |
|
being skipped when checking for a possible empty match (negative lookaheads |
| 82 |
|
and both kinds of lookbehind were skipped). |
