+@Defreq {nop, [@Var{anything}]}
+Interpret @var{anything} as if it were an input line.  @code{nop}
+resembles @samp{.if 1}; it puts a break on the output if @code{anything}
+is empty.  Unlike @code{if}, it cannot govern conditional blocks.  Its
+application is to maintain consistent indentation within macro
+definitions even when formatting output.
