Bug#1053560: meld: Search and replace pattern for newline differs when using replace vs replace all

[Moritz Gericke]

Package: meld
Version: 3.22.0-2
Severity: normal
X-Debbugs-Cc: xmoexdev at gmail.com

Dear Maintainer,

   * What led up to the situation?
        I was using meld and wanted to modify long lines via
        meld's search-and-replace to be able to diff them
        visually.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
        I entered the following line: xaxaxa
        Then hit CTRL+H, entering a in the search field and \n
        in the replace field. I checked the Regular expression
        flag. Then I hit replace once and replace-all once.
   * What was the outcome of this action?
        The text transformed in the following way:
        x
        x\nx\n

   * What outcome did you expect instead?
        I expected the following:
        x
        x
        x
