/**
* Create a filter that executes an external program or script
* A filter def can look like.
* exec someprog -v -t " h i j";charset= xx; mimetype=yy
* We don't support ';' inside a quoted string for now. Can't see a use
* for it
* A filter def can look like:
* exec someprog -v -t " h i j";charset= xx; mimetype=yy
* A semi-colon list of attr=value pairs may come after the exec spec.
* This list is treated by replacing semi-colons with newlines and building
* a confsimple. This is done quite brutally and we don't support having
* a ';' inside a quoted string for now. Can't see a use for it.
