I don't know what you two are fighting about here.

What looks like a space in front of the "a" of answer, is just empty
space in the glyph of the "$B!"(B" character (ideographic comma), which can
be seen when showing it between bars like this: |$B!"(B|
Therefore, the rule in 5.0 CL X (AL | NU) has the effect of preventing a
break which is a significant problem for Asian text that was overlooked
when the rule change for 5.0.0 was accepted.
I am told that this will be fixed in 5.1.
PS: whether or not "before, after" allows a break after the comma and
the following space (2 characters) is beside the point for Japanese
text, which customarily does NOT have spaces.
