Creating gist failed: 422 Unprocessable Entity

[ghost]

With the latest gist gem:

gist-3.1.0.gem

And older ruby version:

ruby 1.8.7 (2012-02-08 patchlevel 358) [x86_64-linux]

I get an error when I try this:

require 'gist'
Gist.write( File.open("quiz.rb"))

Creating gist failed: 422 Unprocessable Entity

Then it exits.

As a user, I do not know what this error means or what to do now.

I can't gist upload this file, but if I do it via the browser manually, all works fine.

Could the message be more helpful so that a new user understands what to
do next in order to solve this problem? From the message I assume
that something may be invalid in quiz.rb

With the same ruby and gem version I get this error when trying to use path, not just file:
$ gist folder/file.py
Which was kind of surprising.

Try pulling 963a5f6 from pull request #93 to fix the path issue. The API usage issue might be an authentication issue, since the GitHub API seems to spit 422 errors back when almost anything isn't quite right.
