[Vimprobable-users] Improve handling of file parameters

[Morgan H. <mt...@gm...>]

Greetings,

I look at a lot of test generated html output and the like, so I
frequently hit problems with file paths. Because of the URI, things
would only open properly if I provided a full path, or something that
would be expanded by the shell into a full path such as
~/html/index.html. Modified to use realpath() to fix this issue. It
would also fail to detect file parameters without a "/" in the path
(e.g. "index.html"), so changed to use stat() instead of looking for
"/" or "./" when determining if an argument is a file. This takes care
of any issues I have run into with using vimprobable to view local
files.

Regards,
Morgan
