Documentation

The maximum number of changes to possibly amalgamate when undoing changes.

The undo command will normally consider "similar" changes
(like inserting characters) to be part of the same change. This
is called "amalgamating" the changes. This variable says what the maximum number of changes considered is when amalgamating. A value of 1 means that nothing is amalgamated.
