OK, maybe I was wrong. We could revert my change and add an explicit note to the manual regarding the indexation convention used. Anyone else have thoughts on this? Part of my motivation for the switch was that if you give a restriction such as "a[1] = 0" (with a single index) this means that all EC coefficients in equation 1 are restricted to zero, or variable 1 is weakly exogenous. And it seemed more intuitive that if you give just one index it should be read as the leading one, not the trailing one. However, I take your point that this is a matter of convention; all that really matters is that the manual is clear on what we're doing. (Either way, I don't want to mess with our existing \beta indexation at this point.)
