The thread then diverged towards my "BTW" remark. So getting back to the
original question, should it go into 'extra'?
I don't have strong feelings either way. The "cheat sheet"
implementation of convolve is just a one-liner, which might suggest
that it's hardly worth adding a convolve function in its own right.
On the other hand the need for, and sizing of, the zero vector to be
appended to the first argument to filter() may not be transparent to
many users, so maybe it's worth hiding that.
