Help: Remove over-precise clause.

Browse Source 
Section "Variables References" said that environment and cache
variables are "evaluated in the same contexts as a normal variable
reference". The reader has to guess what "contexts" means in
this context. Probably "inside a Quoted Argument or an Unquoted
Argument", exactly as for ordinary variable references.
But this is exactly what the reader would tacitly assume anyway.
Therefore I think the removed clause was unnecessary, and possibly
more confusing than helpful.
