- update health check

Some languages that are difficult to parse via Treesitter may
incorrectly include whitespace lines at the end of regions. This can
makes the calculated folds sub-optimal.
To recitfy, use a custom directive (trim), to calculate the range with
the trailing whitespace lines removed. Note this only works if the
region end column is 0.
Also added folds for Make.
