[ELPA Syncer]

branch: externals/xelb
commit 85e407448e4e73f420335df96313cbd6c9c2431c
Author: Steven Allen <steven@stebalien.com>
Commit: Steven Allen <steven@stebalien.com>

    Switch back to the Emacs 28 pretty-printer function
    
    If we're running Emacs 29+, use the pretty-printer function from Emacs
    28 for consistency. We can remove this once we can guarantee that all
    development will happen on Emacs 29+.
    
    * el_client.el (xelb-parse): Force emacs-28-style pretty printing.
