[elpa] externals/denote 984c3feb24 2/6: Make denote-rename-buffer do nothing if there is no underlying file

[ELPA Syncer]

branch: externals/denote
commit 984c3feb24907a24ee59103bed7fc5a87145dbbb
Author: Protesilaos Stavrou <info@protesilaos.com>
Commit: Protesilaos Stavrou <info@protesilaos.com>

    Make denote-rename-buffer do nothing if there is no underlying file
    
    If the buffer-file-name is nil, then we do not want to proceed because
    'denote-file-has-identifier-p' will return an error.
    
    This should fix the issue with epub files opened with nov.el, as
    reported by arsaber101 in issue 229:
    <https://github.com/protesilaos/denote/issues/229>.
