Aha, thanks, that was helpful in the sense that I get an idea where to
look.

According to git blame (not sure how reliable that is) the function
TeX-evince-sync-view, was written mainly by you and Mosè

The funny thing is that evince seems to have no configuration option for
an external editor, making the sync feature somehow opaque.
