An editor being awkward should be limited (8)
I believe the answer is:
rationed
'limited' is the definition.
(rationing is a kind of limiting)
'an editor being awkward' is the wordplay.
'being awkward' is an anagram indicator.
'an'+'editor'='aneditor'
'aneditor' anagrammed gives 'RATIONED'.
'should be' is the link.
(Other definitions for rationed that I've seen before include "Apportioned out" , "Restricted a scarce commodity" , "Limited (a supply)" , "issued shares" , "Allowed fixed quantity only as in times of scarcity" .)
