Hmm, if I wrap that in @samp, then it renders as:

 We place optional portions of a packet in '[square brackets]'; for example, a template like ‘c [addr]’ describes a packet beginning with the single ASCII character ‘c’, possibly followed by an addr. 

Those '' around [square brackets] seem off to me there.  The original author must have wanted the
rendered text without the single quotes too, since they didn't use @samp and they certainly
looked at the rendered output back then.  So given @r are nops, I think we should just remove them.

That results in:

 We place optional portions of a packet in [square brackets]; for example, a template like ‘c [addr]’ describes a packet beginning with the single ASCII character ‘c’, possibly followed by an addr. 

which IMHO looks better.

If you dislike that, I noticed that:

 https://www.gnu.org/software/texinfo/manual/texinfo/html_node/Command-List.html

says:

 Square brackets, [ ], indicate optional arguments

We could switch to a similar wording.  I kind of like the original better, but
this is a very tiny detail, of course.

Let me know what you think.
