The info tends to get cut off. Using emacs in a 80 column window shows
the style part (the stuff within parentheses) and the counts more to
the left.
Also, mg seem to compute the percentage based on line numbers and cursor
position. But emacs computes a number based the top line being shown
and the total number of lines in the file. Emacs updates the number
only when the top line changes due to cursor or other movement.
