Does it match a line ending with >>? The StrongED Help on ~
says

    "A" ~ "B"  : Matches "A" if the following character is not "B"

but it does not say what happens if there is no next character, and
this makes it incomplete. It would make pattern syntax a lot easier if
it counted "beginning of string" and "end of string" as characters.
Using ^ and $ as these pseudocharacters what we want is

  (^ or not >) >> ($ or not >)
