History expansion is part of readline, and knows next to nothing about
shell syntax. It knows a little bit about the shell-like quoting that is
common to many Unix applications, but not much else. There is a minimal
hook function that allows applications to suppress expansions the history
library would ordinarily perform, so maybe it can be extended to understand
these constructs.
