Problems with 'set editor'

[Steve Crane]

Earlier this week someone recommended adding

  set editor ="vim +'/^[ ,\t]*> --/,/^-- /-2d'"

to .muttrc to strip out the signature on a reply so I implemented this.
It works fine but but if the regexp is not found (when sending a new
message for instance), I get an error message and must press return to
continue.  This is rather irritating and I was wondering if there is any
way around it.
