As a workaround, you might try changing your command to one of these:

% { xsltproc style.xslt - | grep … } <file_200701.xml
% <file_200701.xml xsltproc style.xslt - | grep …
% () { xsltproc style.xslt "$@" | grep … } file_200701.xml

This should make it easier to edit the filename, because it'll be at
the start or end of the command line.

Regarding your other points, I'll defer to others.

Cheers,
