"DEG" should be "DEGS" - I've updated the manual.

In fact there's one standard list of units for angular quantities, and
percentages are also supported for clinos as a special case.

I've added MINUTES as supported in the manual (it's been supported this for
ages, so fixing the manual to document it seems better than removing this
support).

Thanks for spotting and reporting these.

I think it would be useful to add your test files to the Survex test suite,
so any regressions get caught sooner.  Are you happy to contribute them?
If so, probably best to let me know when you've completed building them
and I can add them in one go.
