- Fix extra ] spotted in online doc by emigas.
- Remove another ] introduced in Hearder syntax in r1588244
- s/variable/varname/ to match the text below it.
- Turn the syntax of both Header and RequestHeader to be:
   header [value [replacement [early|env=[!]variable|expr=expression]]] 
in order to match the code.
This removes the ambiguity of expr=<something> which can now be used in 2 different places in the syntax.
- Also remove the space in 'expr= value' in compatibility note, to help distinguish between the two
