Could you send it as a context patch?

Hmmm....no, C-h f occur RET says:

   Each line is displayed with NLINES lines before and after, or -NLINES
   before if NLINES is negative.

So negative values are not meaningless and neither is zero.  Zero is
unnecessary in the default config, but if the user has set
list-matching-lines-default-context-lines to a non-zero value, then even
zero is useful (I'd even say, it's *very* useful in that case).

Which is why I suggested to use a non-numeric value (just a C-u) to
trigger the "collect-string" behavior.
