This seems like a misfeature to me. It makes sense for
a regular expression to give special meanings to backslash
sequences, because it's a sublanguage with its own syntax.
But I can't see any earthly reason to do that with the
*replacement* string, which is just data.
It looks like a feature that's been blindly copied over
from Perl without thinking about whether it makes sense
