A pathname value in a clean/smudge filter process "key=value" pair can
contain the '=' character (introduced in edcc858). Make the user aware
of this issue in the docs, add a corresponding test case, and fix the
issue in filter process value parser of the example implementation in
contrib.

Yeah, I just naturally assumed it would work this way, as it's pretty
standard in our other key=value protocols. But certainly it's reasonable
to document it (and to keep the t0021 filter as a good example).

There are diplomatic ways and other ways to say the same thing, it
seems, and yours is almost always more diplomatic than mine ;-) 

My knee-jerk reaction last night that I didn't send was "I would
understand if the new test were about quotes or whitespaces, but is
it even useful to make sure that the value can have an equal sign in
it?"
