[ELPA Syncer]

branch: elpa/d-mode
commit e19d7040dbc5d59d3594d113b30d896f56239b1a
Author: Dmitri Makarov <dmakarov@alumni.stanford.edu>
Commit: Dmitri Makarov <dmakarov@alumni.stanford.edu>

    Closes #21.
    
    Fix the regexp pattern that matches backslash chars in a back-quoted
    string literal.  This pattern is used by the function that applies
    mode-specific syntax attributes.
    
    Add a test case that checks the regression.  (The testing infrastructure
    will be updated soon to validate the test case.)
