Good question.  So what is the right expansion for %{l}:

1) backslash
2) \b\a\c\k\s\l\a\s\h
3) "\b\a\c\k\s\l\a\s\h"
4) any of the above

You could argue that %{l}@%{d} (in an exp, for example) should be a
syntactically valid email.  And leaving the quotes intact would be the
easiest way to ensure that.
