for what's supported. This simplified the roff_cond() function quite
nicely. From a bug report by uqs@.
Added regression test based on bug-report example by uqs@.
Also added ROFF_DEBUG to see what the hell the parser is actually doing.
Obviously turned off by default.

Fixed flushed-out condition of \} causing subsequent arguments to be
truncated, when in fact the whole line should be passed through (if the
conditional succeeds) to the front-end and the \} ignored there.
Added regression test of this behaviour.

Using `if 0' as a baseline for "false" roff instructions instead of `if t'.

conditional-negative context so as to preserve structural integrity.
Initial "rules" (deny/allow) are now inherited for future work in
evaluating conditionals.
Lint-fix noted by Joerg.
Added regression tests for zany constructs.

and documentation for the same.

Check against some strange `.if' constructs I missed.
Added initial roff.7 manual.
