Hi Tassilo,
thanks for your reply and information you provided. My patch was
based on the assumption, in turn based on my experience, that no DVI
viewer had implemented SyncTeX forward/inverse search, assumption you
proved false. I still can't do DVI forward/inverse search with Evince
but I trust you can.
Can we at least stress in the manual that one should verify the viewer
supports the same forward/inverse method chosen by
`TeX-source-correlate-determine-method'? Something like this
