[ELPA Syncer]

commit eb7623fb3b23afec25619a76adab6bab5e338bf2

    Handle mmm-mode '' prefixes better
    
    Sometimes we have variables that look like attr'' that Nix handles as a 
name but
    mmm-mode thought was a beginning of a multiline string. This adds some cases
    handling those names to mmm-mode detection.
