[Gregory Heytings]

branch: scratch/fix-locked-narrowing
commit a6cd4553d48aff1d241d54d62dc1b39b3ff541e0
Author: Gregory Heytings <gregory@heytings.org>
Commit: Gregory Heytings <gregory@heytings.org>

    Rename two long line optimizations variables
    
    * src/buffer.c (syms_of_buffer): Rename two variables.
    
    * src/xdisp.c (get_locked_narrowing_begv):
    (get_locked_narrowing_zv):
    (handle_fontified_prop): Use the new names.
    
    * src/keyboard.c (safe_run_hooks_maybe_narrowed): Use the new
    names.
