Comment 1 for bug 1095290

Well, actually... we've had people who have wanted to use different arrow characters, for whatever reason. Having it be translatable makes it easier to supply a different tpac.po file. Whether it's translatable or not, it should at least be consistent, though, which it is not currently. Also, I dunno - would it make sense for a right-to-left language to want to put the arrow symbol on the other side and facing the other way?

Aside: in your branch, was there a reason to wrap the arrows in <span> tags? That seems to introduce extra markup for no discernible reason.
