Ultimately it's G_recreate_command() which needs to be fixed[1]. You
can get it 99% right by just putting single quotes around each
argument; to get it completely right, you also have to replace any
single quotes with "'\''" (quote-backslash-quote-quote).

[1] I'll look at it at some point.

Also, this is a warning sign regarding the syntax. Even though the
issue is specifically addressed in the "NOTES" section of the d.area
manpage, I wouldn't be surprised if we get "bug" reports due to users
failing to quote the argument (there's already been one case of a user
attempting to use spaces in a multi-valued argument).
