commit 80fccd4290ae134bd1b3d377f134bb9143b68b43

Commit: Eli Zaretskii <address@hidden>

    Avoid losing the buffer restriction in flyspell-mode
    
    * src/intervals.c (get_local_map): Don't allow C-g to quit as long
    as we have the buffer widened, to make sure the restriction is
    preserved.  (Bug#28161)
