If that were a no-op, I wouldn't write it (why would I write something
that does nothing???).

In fact, it does *not* do anything in this particular situation either.

Or are you thinking about

   .TH TEST 1
   .IB italic bold\c

which prints the tree words in three different fonts, with no
intervening whitespace on the output side?

Yup. You got what I had in mind. Sorry for the nonsense. I'm happy that at least my confusion triggered an interesting discussion about \c :-}

Sooo, both "no-op escape" and "dummy character|escape|whatever" seem good things to me.

On a tangent, i just noticed that


And yes, the different behavior of

.B foo\c

between groff(1) and mandoc(1) surprised me too. I, as you, thought that the intuitive behavior would be as [.BR foo bar], and reported it to the mailing list a few months ago.
