Rudimentary implementation of the roff(7) .while request.
Needed for example by groff_hdtbl(7). There are two limitations: It does not support nested .while requests yet, and each .while loop must start and end in the same scope. The roff_parseln() return codes are now more flexible and allow OR'ing options.
