[Groff] Typo in HTML documentation § 5.7?

[Carsten Kunze]

Hello,

maybe there is a typo in "5.7 Manipulating Filling and Adjusting" section 
"Register: \n[.sss]".  In the sentence "Note that the \h escape produces 
unbreakable space." the "h" maybe should actually be a space (in the context of 
that section).
