Strongs matching doesn't play as nicely with "Match based on stems" for Biblical key terms as it could.

The 'Match based on stems' flag in paratext reduces false positive matches in the key-terms checking - it means that only word-forms that have been marked as having a certain stem will match.

Unfortunately for producing nice output in ptxprint, using this flag means that the stem is in the biblical terms renderings list with no asterisk or other marker, which users of paratext can eventually get used to but it would be confusing for most people.
e.g. in Romani, 'give' is used in many phrasal renderings, (such as 'give hand' = assist, 'give way' = release), and the stem is 'd-'.
Thus the key term for release might have "d drom (give way)".

Paratext obviously contains code that searches the word entries and realises that 'd' is the stem in this case. It would be nice if PT had provided some way to specify that this word is the stem, but as it hasn't, it would be good to notice the above-mentioned flag and provide some mechanism to look through the wordforms and spot that 'd' should have a * or hyphen appended to it.
