sshsha.c: remove rogue 'got up to here' comment.

How silly :-) I use comments like that to record my progress when I'm
going over a whole source file making some mechanical change, but I
normally manage to avoid accidentally leaving them in the final
version of any commit. Remove this long-outdated one.
