commit 3ddf995f9c9651d8ca8a6d23655e956cb807fb36
Author: Norihiro Tanaka <address@hidden>

    dfa: more simplification of dfaexec_main
    
    * src/dfa.c (dfaexec_main): Failure at an acceptable position and demand
    to build state is unlikely.  So go next loop without checking them after
    a newline.  This commit induces no semantic change.
