A hyphen could be confusing as it may be treated as a literal part of
the code. I doubt this has come up much before as people will rarely
use @- inside @code. Given that people are only putting in @-
deliberately then it may be harmless to make it print a hyphen.
However, line breaks at _ and - are allowed inside @code, without any
extra hyphen being printed. How can the user distinguish between
hyphens that are taken literally and those that are only for word continuation?

Maybe we could try to print hyphens inserted with @- in a roman font,
and see if it is distinguishable enough from a hyphen in the tt font.

We should test both in any changes we make.
