One of the design principles of that feature is that it should be as transparent as possible, and it is. The point of adding a variable to control the feature was to avoid introducing an arbitrary constant at the C level, and also to allow users who really enjoy slowdowns to turn these optimizations off

Then why is it a number and not a boolean? A number that I don't know how to change is as good as a constant.

You don't have to change it.

Vertical-motion is not slow anymore.

Could you please show a file where I can appreciate a noticable speed-up in vertical-motion?

Are you kidding?  Try, for example:


No type M-> C-p. Before the merge this takes about 50 seconds (about 20 seconds for M-> and 30 seconds for C-p). Now it is instantaneous. And that's only a moderately large file (20 MB). Try the same with a 1 GB file, and M-> will never end.

Meanwhile, could you please fix the build breakage introduced by a29a3ad55d?
