Running sage-mathematics-6.4.1-9 on an up-to-date Arch Linux system, I've just noticed that the internal help is broken.

To reproduce, start sage and type any command name, followed by "?", then enter. Example:

$ sage
┌────────────────────────────────────────────────────────────────────┐
│ Sage Version 6.4.1, Release Date: 2014-11-23 │
│ Type "notebook()" for the browser-based notebook interface. │
│ Type "help()" for help. │
└────────────────────────────────────────────────────────────────────┘
