Hmm... when I introduced `tex-cmd-doc-view` it just used

    (pop-to-buffer (find-file-noselect file))

then when Sam Steingold introduced `display-comint-buffer-action` (in
commit 18b680cfd177) he used it there as well, but I suspect this was
a mistake because that command does not at all work like a comint thingy
(my guess is that he's an AUCTeX user and just assumed that
`tex-cmd-doc-view` is like other `tex-cmd-*` thingies).

I'm not sure it's harmful to use `display-comint-buffer-action` or
`display-tex-shell-buffer-action` there (e.g. I haven't noticed it being
a problem in my own use since Sam's patch), but it doesn't seem
necessary nor very natural (it's just not a "tex-shell" or "comint"
buffer, it's a normal file buffer).
