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).
