Hi @spf13,

Sorry for my earlier premature recommendation for the fix. It turns out that this patch has undesirable side-effects: Specifying full path to the executable, or renaming the executable, would make it ignore any command-line arguments. Using hugo as example:

    $ ~/go/bin/hugo --help

    $ mv hugo hhuuggoo
    $ hhuuggoo server

All subcommands and flags are ignored...

I discovered this problem when trying to sudo ~/go/bin/hugo genautocomplete. At first, I thought it was the sudo, but it turns out sudo hugo works well; the problem came from the full path to the hugo executable.

@apriendeau, any ideas of an alternative solution? :-)
