[tor-commits] [tor/master] Tweak coverage-html target

commit 98541f2892335a5a512a6c01b2f2227bde1d649e
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>

    Tweak coverage-html target
    
     - Don't try to rm -rf the directory before we start: somebody might
       have set it to ~, which would be quite sad.
    
     - Always quote the directory name
    
     - Use 'make reset-gcov' before running tests.
    
     - Use 'make check', not ./src/test/test
