standard parameters (most notably "charset") to keep plugins
decent.
Note2 that this method preserves the case of the parameter
value returned. So, if the parameter you want to use defines
the value to be case-insensitive (such as the smime-type
parameter), you need to make sure you do the casemap yourself
before comparing to a reference value.
