[elpa] externals/dired-preview 38fab3d419 38/67: Use 'file-regular-p' instead of 'file-exists-p'

[ELPA Syncer]

branch: externals/dired-preview
commit 38fab3d4198e5df2e469ddf3dfd6f0c9945b55ac
Author: Protesilaos Stavrou <info@protesilaos.com>
Commit: Protesilaos Stavrou <info@protesilaos.com>

    Use 'file-regular-p' instead of 'file-exists-p'
    
    This way we do not try to preview named pipes and sockets.
    
    Thanks to Karthik Chikmagalur for bringing this matter to my
    attention:
