Italicise primes and brackets in state res desc (#1043)

Browse source 
* Italicise primes and brackets in state res desc

I don't like it but it seems to make things look decent in Firefox.
This is probably good enough---we're not Knuth, after all.

Additionally I have avoided the use of `*E*'s` as in "E's prev_events"
since the apostrophe looks poor here.

Resolves #774.
An alternative to #1040.

The room state *S′(E)* after an event *E* is defined in terms of the
room state *S(E)* before *E*, and depends on whether *E* is a state
event or a message event:
- If *E* is a message event, then *S*′(*E*) = *S*(*E*).
- If *E* is a state event, then *S*′(*E*) is *S*(*E*), except that its
entry corresponding to *E*'s `event_type` and `state_key` is
replaced by *E*'s `event_id`.
- If *E* is a message event, then *S′(E)* = *S(E)*.
- If *E* is a state event, then *S′(E)* is *S(E)*, except that its
entry corresponding to the `event_type` and `state_key` of *E* is
replaced by the `event_id` of *E*.
