Feedback- pipeline usage, --field support

[Robert Ames]

Please see the attached transcript illustrating why detecting pipeline usage is helpful, and the clarity + utility of "--field / --clip" improvements.

These capabilities are included in the patches I submitted a few weeks ago... I haven't heard anything back about them, but am still interested in getting them included in the next release.
