Spurious space around parentheses

[dbuenzli]

It seems that the merge of #782 (available in the latest odoc) was done with little attention to typographic details.

New spurious spaces are being inserted around parentheses in some type definitions here are a few examples:

val pf : Format.formatter -> ( 'a, Format.formatter, unit ) format -> 'a
val map : ( 'a -> 'b ) -> 'a list -> 'b list

In other contexts the parentheses are fine e.g.:

val exn_backtrace : (exn * Printexc.raw_backtrace) t
val assoc : 'a -> ('a * 'b) list -> 'b

Fixed by #832, thanks @panglesd !
