terminal: regression: char printed to wrong column

Browse source 
When term_print() was implemented, it introduced a regression where
printing a character when the last cursor was in the last column on a
line would print the character in the wrong column.

This is because term_print() retrieved a pointer to the current
cell *before* line wrapping (and possibly inserting empty cells).
