|Subject:||bug#39608: defun occur does not use a coherent value for default-directory (fix included)|
|Date:||Fri, 14 Feb 2020 19:26:52 +0000|
When occur creates an *Occur* buffer, the default-directory variable is implicitly set to the default-directory of the buffer the occurences came from.
When occur REUSES an existing *Occur* buffer, it does not update the default-directory variable.
Following is a patch for emacs 26.3:
