R devel - Feb 2006 - Improve error message for bad NAMESPACE file?

If a user mis-types a directive in the NAMESPACE file, the error
message is quite cryptic.  If it was possible to report the offending
line/text that would likely give a valuable clue to the user.

Try putting the following line in NAMESPACE

foo("bar")

Then R CMD INSTALL says,

* Installing *source* package 'goodbye' ...
** R
** preparing package for lazy loading
Error in gettext(domain, unlist(args)) : invalid 'domain' value
Execution halted
ERROR: lazy loading failed for package 'goodbye'

I suspect this line in namespace.R:

                }
                stop(gettextf("unknown namespace directive: %s",
deparse(e)),
                     call. = FALSE, domain = FALSE)

Does domain=NA solve this?
