Log Message:
-----------
Fixed condition of `\}' closing a conditional at the start of the line.
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.

+functions calculate the complementary error function of
+.Fa x ;
+that is
+.Fn erfc
+subtracts the result of the error function
+.Fn erf x
+from 1.0.
+This is useful, since for large
