It's worse than that: some institutions use "semester" for third-of-a-year
intervals (also called trimesters).  I've also heard of places that use a
fairly standard Sept-to-May calendar but call summer classes a third
"semester", even though it's shorter than their regular class sessions.

I don't think we should accept a patch along this line, because it assigns
a very specific meaning to "semester" that does not square all that well
with real-world usage.
