I would expect it to work like gf (which itself is inconsistent).
If I put the cursor over "later" in the paragraph above and type
gf, I get a persistent error message in the command line:
E447: Can't find file "later" in path
If I visually-select "later" with viw and type gf, I get the same
message, but it appears for only about one second. It seems like it
should also persist, but at least I see it and can look in :messages
to read it again.
'cmdheight' doesn't seem to affect the behavior of gf, but setting
'noshowmode' does "fix" it. It would be nice if visual mode could
be made smarter about clearing "-- VISUAL --" when that message has
been overwritten, or at least leave it for a second or two as
{Visual}gf does.
