Status: RESOLVED WORKSFORME

Description

[Jeff Walden [:Waldo]]

Looking at bug 1101265, it's extremely hard to be sure what to pass where, for what purpose.  This is doubly true if the argument there were made non-optional (as I very nearly suggested).  If that were done, one method might have recursive calls passing down the provided argument *and* separate calls ignoring it entirely, with the logic for each determination quite unclear.

This desperately needs cleanup and simplification, even if (as seems semi-likely) the current seek-backward-and-retry technique continues to be used.
