cmu.edu filter silently breaks some forms

This bug is filed against the production version of https://www.eff.org/https-everywhere/atlas/domains/cmu.edu-2.html

HTTPS Everywhere silently breaks pages within the http://www.cmu.edu/graduate/professional-development/ directory, because these pages embed HTTP forms that are available in HTTPS format (by changing http://cmu.savvior.com/... to https://savvior.com/cmu/... in form URLs) but the secure versions are not currently active. The workaround is to use HTTP only for browsing that portion of cmu.edu, but the rule (when enabled) silently prevents that.
