(cherry picked from commit d3cea8a4)

So you now get
enum A { a = 2,
         b = 3,
       };

This will allow much faster indenting of selected areas as the state
doesn't have to be checked again for every line.

Updating the text cursors that the extra selections are based on can
get quite slow if there are changes in a lot of positions - like when
reindenting a file.

Dropping some text cursors can increase performance significantly in
these cases.

Done-with: mae

There are cases like when editing, or when jumping to a line, where we
shouldn't cut it though (so we don't).
