“Error: Cannot have more than one mode.” error is confusing

Error: Cannot have more than one mode.
~/.freshrc:10:   fresh https://gist.github.com/5406589.git .gitconfig --file

You may need to run `fresh update` if you're adding a new line,
or the file you're referencing may have moved or been deleted.
Have a look at the repo: <https://gist.github.com/5406589.git>

I didn't read the full error and thought there was something wrong with the repo and it couldn't find the file or something. We probably don't need the second paragraph for this error.
