[PATCH] vcs_info quilt: More documentation of '%Q' and 'use-quilt'.

[Daniel Shahaf <d.s@daniel.shahaf.name>]

---
'%Q' was missing from the reference documentation.

'use-quilt' was missing from the running prose.  Adding it breaks the flow
somewhat, but I didn't see a better option.

Cheers,

Daniel
