Array.ticks returns ticks outside domain

[dson]

Array.ticks sometimes returns ticks outside the domain. This is inconsistent with the documentation, that says: each returned tick t satisfies start ≤ t and t ≤ stop. This behavior was introduced in 2.5.0, and probably caused by commit f5883f6.

Example, where tick 3 is outside domain [0, 2.2]:

array.ticks(0, 2.2, 3) // [0, 1, 2, 3]

Confirmed (both the bug and the commit reference).

Good find!
