attachInterrupt() Mode explanation has confusing spacing

[cattledogGH]

In attachInterrupt.adoc there text with spacing which doesn't not make clear that HIGH is valid for Due, Zero and MKR1000 boards only. The space should be after the line for FALLING and not right before the line for HIGH.

Four constants are predefined as valid values:
LOW to trigger the interrupt whenever the pin is low,
CHANGE to trigger the interrupt whenever the pin changes value
RISING to trigger when the pin goes from low to high,
FALLING for when the pin goes from high to low.
The Due, Zero and MKR1000 boards allows also:

HIGH to trigger the interrupt whenever the pin is high
