[bug #42675] \} considered as macro argument regarding register .$

[Bjarni Ingi Gislason]

Follow-up Comment #4, bug #42675 (project groff):

  The examples do not show a bug in the software.

  They can serve as an exercise in understanding, to give people an
opportunity to test their "solving" skills, understanding of concepts.

  So nobody should "publish" a solution, as that deprives the readers
to tackle the exercise on their own.

  Otherwise their "brain software" does not grow to be better.

  Maybe this could be put in a file called "EXERCISES".

  This issue shows (me at least), that the examples are

1) too simple in one aspect

2) too complicated in another aspect.

  And people should start (to teach themselves) to ask themselves
questions to help themselves solve "mysteries".
