[Groff] OT: \} considered as macro argument regarding register .$

[Carsten Kunze]

Hello,

(may be off topic)

Why is \} (end of conditional block) considered as a macro argument regarding 
the register .$ ?
It may not be best style, but often \} is written behind the last request of a 
block. There are warnings for doing this for requests like e.g. .ds, but that 
it also increases .$ is not expected. Has this really been intended by the 
nroff author?
