groff doesn't have \h[...] but, following the original, \h'...' only.

I wonder why Clark hasn't allowed this.  Any idea?  It should be quite
easy to allow [ and ] for all escapes as delimiters also.  I don't
see syntax or compatibility problems firsthand.

Additionally, groff doesn't have \D'b ...' -- what is this?
