Your suggested names are all valid identifiers.  The "-" gives strings 
that are not.  That's intentional; the help system relies on it.  You 
find "utils-deprecated" using deprecated?utils.

If your highlighter has problems with the "-", then don't bother 
highlighting.  Those names aren't very common.  Or...

...you could do it by context.  codes-deprecated will only show up in 
*.Rd files as a possible search term:  an alias, or a name.
