@kha `mkAntiquot` is used in all categories. I removed
`termParser (appPrec + 1)` to avoid nasty interactions between
`termParser` and the surrounding category.
This commity ensures the antiquotation prefix is one of the following
forms `$<id>` or `$(<term>)`.
I made the two cases look like term syntax because I didn't want to
change your expander. We should fix this next week.
