measure: convert to the new option and verb parsers

Previously, we had a nice third 'UKI PE Section' column with the section
names. This is now moved into the help strings, which means that the nice
alignment is lost. Previous behaviour could be restored by constructing
the table manually, but I'm not sure if this is worth the trouble.
