Well, on the one hand, I understand what 18 kill-sexp does.  It kills 18
sexps, and this is fine if you want to kill that much sexps.  On the
other hand, what does 18 how-many means?

You're asking for a differentiation between a positive and a negative
argument, but what is the *purpose* of the value of this argument?

My proposal uses the prefix argument as a flag, not as an integer value.

> keep|flush-lines, how-many could do the same, e.g. `M-- M-x keep-lines'.

M-- puts a prefix of -1, so M-- M-x keep-lines would be the same as M-u
M-x keep-lines.


I hope I don't have misunderstood what you proposed.
