            Bug ID: 107916
           Summary: EDITING:  Find & Replace Backreference Fails using
                    Replace All and \b
           Product: LibreOffice
           Version: 5.2.6.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org

In certain situations, using a regex with groups and backreferences in Find &
Replace will cause the backreference to insert "$1" instead of the actual text.

Steps to Reproduce:
  In Writer:
    1.  In a document, insert the following text:
           .AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA.
           .BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
           CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC.
           DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD
    2.  In Find & Replace, use the following (with regex activated):
            Find: \b([0-9a-f]{32})\b
            Replace: $1
    3.  Note that hitting "Replace" will replace the strings of letters with
themselves as expected.  Then note that hitting "Replace All" will replace the
A and B strings with the text "$1".

Replace all results in Writer:
           .$1.
           .$1
           CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC.
           DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD

Libreoffice Calc performs the "Replace All" as expected:
           .AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA.
           .BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
           CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC.
           DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD
