Set curwp->w_markline after clearmark in markpara

[bscuron]

Fixes bug where the current markline is not reset after being cleared.

This makes it possible to now mark a region, and use apply-macro-to-region-lines since the markline is now set in the correct position:

Interesting, could you please provide a sequence of commands to reproduce the problem?

It happens when you press M-h to mark paragraph. Here is a screencast showing me logging the markline value after pressing M-h before the fix and then after the fix.

Awesome, thank you so much!
