Maybe I've just got my head deeply in the sand, but I don't understand
what the alternative to E'' supposedly is. How am I supposed to write
the equivalent of E'\t\n\f' without using E''? The
standard_conforming_strings syntax apparently supports no escapes of
any kind, which seems so hideously inconvenient that I can't even
imagine why someone wants that behavior.
