Screws up angle brackets

[vphantom]

Example paragraph (but where angle brackets are actual, not HTML escaped as below):

begins with "<?oc" it is trailing "?>". This

NDlite outputs what we would expect, but inserts a backslash before the first closing quote and before the second opening quote:

with "<?oc\" it is trailing \"?>".  This

This seems to be an interaction between the quote and bracket escapings, because changing the first < to a > removes the backslashes, but also leaves the first and last quotes of the 4 intact, and the 2 middle ones styled.

Removing the first < entirely solves its quoting, but leaves the second's quoting completely unstyled.
