Did this a couple of days ago, but must have missed the final step.

Saw as よお for sense  4. suggest splitting out 4 and 5 together with よー

No further comments. Closing.

Fine, but I suggest trimming back the notes as they rather swamp the entry. The "食べる→食べよう" spells out the context.

Thanks for the clarification. I was going to argue these senses shouldn't be included because it's a conjugation for only a limited set 
of verb classes (一段 and する/くる?) and we don't have similar entries for -そう, -とう, etc. which should be equally valid... but I 
realized these senses are actually included in daijs' and daijr's よう entries and we do actually have an entry for "た" ("indicates past 
tense") in JMDict as well. 
_
My preference would still be to follow GG5's example to not include these senses and also not have an entry for た, but I guess that'd be 
a topic for the mailing list instead of the comment section of this one entry.
_
In the meanwhile, I've tried improve the 3 senses because I don't think the definitions/notes were very clear. I've moved the previous 
glosses into usage notes and added actual glosses. To what extent the glosses are helpful, I'm not sure, but until the separate issue of 
glossless senses are resolved, maybe this will do. I also moved the previous sense 1 to sense 3 as I think it's the least common aux-v 
usage (if that's indeed the correct PoS).

"verb stem" - is this the right term? I forget
