vis-open: fix for absolute and non-existent paths

When the shell cannot find any matching files, the glob is not expanded,
and vis-open will return the absolute path of the current working
directory (because dirname outputs '.'), followed by the filename,
followed by a literal '*'. This commit checks that the final path
actually exists, and if not, exits with status 1.

It also uses text_object_longword for the range to match, so that
absolute paths are accepted, and replaced properly (else it only works
back to the first '/').
