Great, thanks to confirm.

`substitute-command-keys` at least doesn't handle this.

Say you have the file foo.el with 
`read-symbol-shorthands` == (("f-" . "foo-")) and containing definitions
like `f-dothis`, `f-dothat` etc... and a var `f-help-string` containing string 
like
"\<f-map>\[f-dothis]: Description", if you define a function `f-help`
containing (substitute-command-keys f-help-string) it will fail
complaining `f-dothis` is void.
