[Emacs-diffs] master 5fd2297: Make transpose-regions invoke before-change-functions only once.

branch: master
commit 5fd229735384a5fa479466124a181bf7d4ea8dab

    Make transpose-regions invoke before-change-functions only once.
    
    In the case of two non-contiguous regions the same size, transpose-regions 
has
    been calling before-change-functions twice, once for each region.  It now
    calls it just once, for the minimal region spanning both single regions.
    
    * src/editfns.c (Ftranspose_regions): Combine two calls of modify_text into
    one.
