It works, all the while the document remains open in TeXworks,
but as soon as the document is closed TeXworks "forgets" with
which engine the file was formerly associated.  If TeXworks
were to prepend the appropriate engine pragmat to the in-
buffer working copy, then when the user came to close the
buffer he would be prompted "The document ... has been modified.
Do you want to save your changes ?", and assuming that he chose
the "Yes" option (oddly called "Save", for reasons that seem to
escape me), the pragmat would automatically be inserted into
the associated file.
