Subject: Do not read one element past the end of the static const termacts
 array. Bug found by Sevan Janiyan <venture37 at geeklan dot co dot uk> who
 ran the OpenBSD mandoc test suite on Ubuntu on POWER8 (sic!) and reported
 that mdoc/Sh/before.in failed in -Tman mode. If that isn't power testing, i
 don't know...
