GUI keyboard repeat rate suffers with many long lines #1259

Description

@wfaulk

Steps to reproduce

  1. Open MacVim (mvim --clean)
  2. Create a line 80 characters long (80ii<Esc>)
  3. Go to beginning of line (0)
  4. Hold down 'l' and time how long it takes to get to the end of the line (for me, about 3 seconds)
  5. Delete this line (dd)
  6. Create a line 700 characters long (700ii<Esc>)
  7. Make 90 copies of this line (yy90p)
  8. Go to column one, row one (1G0)
  9. Hold down l and time how long it takes to get to column 80 (for me, about 6 seconds)

(This affects insert repeat rate as well as cursor motion.)

(Also, I don't think this was a problem before the recent update to 9.0, but I could be wrong.)

Expected behaviour

The repeat rate shouldn't be affected by the data in the buffer.
