OK, I added .coveragerc and that works. In the process of verifying 
this, I was reminded that there is an overt bug in the html report as 
displayed by Firefox. The fonts used for line numbers 
("class='linenos'") and line text ("class='text'") are slightly 
different and, more importantly, with difference sizes (line numbers are 
larger). So corresponding numbers and text do not line up with each 
other. This makes the J,K hotkeys and missing branch notations much less 
useful than intended. If I use cntl-scrollwheel to change text size, 
both change in the same proportion, so the mismatch is maintained.
