[tor-commits] [tor/master] test/parseconf: Stop ignoring --dump-config failures



commit 4514bfe9c25f3222e0feba29c5129229287f3963
Author: teor <teor@xxxxxxxxxxxxxx>

    test/parseconf: Stop ignoring --dump-config failures
    
    When we added the $FILTER for Windows newlines, we made
    the pipeline always exit successfully, even if tor failed.
    
    Fixes bug 32468; bugfix on 0.4.2.1-alpha.
