"Negative means unlimited" feels unnecessary. Didn't you make "unlimited"
the default anyway?

This description is unclear. Does "-n 2" tell "show 2 commits from both
side", or "show 2 in total"?

When you have room only for N lines, you might have to say (X more), but
you never need to say (1 more). You can fit that omitted one item on that
line instead of wasting that line to say (1 more).
It is unclear from the above illustration as the (1 more) is pointing at
right without having anything newer than that, but I think you meant to do
something like this:
<top
<second
<... (N more)
<bottom
>top
>second
>... (M more)
>bottom
I guess fork-point may be interesting enough that showing the bottom one
like you did might make sense. I am not convinced but we'll see.

\?\+?????
summary_limit=$(expr "$2" : '[0-9][0-9]*$')
or even
if summary_limit=$(( $2 + 0 )) 2>/dev/null ||
test "$2" != "$summary_limit"
then
usage

perhaps.

Don't. The first line of this script says "#!/bin/sh", not bash.
