StrSubstitutor can preserve escapes
StrSubstitutor can now optionally preserve the escape character for an
escaped reference, which is useful when substitution takes place in
multiple phases and some references are intentionally unresolved. Prior
to this change, an unresolved reference `${a}` and an escaped reference
`$${a}` may result in the same string `${a}`, making it impossible for
an additional substitution phase to distinguish between escaped
references and non-escaped references.
