Observation:
when I place the text cursor on a character to the right of the 'p' in qla27xx_ski
p_entry, and I do push-ref, all the references to this symbol, except for the definition of this symbol, are found (shown in References tab);
when I place the text cursor to the left of the 'p', the following message pops up:
Symbol 'qla27xx_ski' not found.
Do you want to search for word matches?
( and, also (already mentioned somewhere in this thread), gui-push-tag finds the definition of this symbol )
