Thanks, I have a comment to this, but in general this is the right
fix, IMO.

You can't: TTY frames cannot discern screen positions with resolution
of more than 1 character.

IMO, 'eq' is not right here: this test should obey the value of
double-click-fuzz, whose units on TTY frames are 1/8 of a character.
