Documentation:
A set of functions used to rewrite the command argument.
Once parsing of a command line is completed, the next step is to
rewrite the initial argument into something runnable.

A module may wish to associate special behavior with certain argument
syntaxes at the beginning of a command line. They are welcome to do
so by adding a function to this hook. The first function to return a
substitute command form is the one used. Each function is passed the
command's full argument list, which is a list of sexps (typically
forms or strings).

You can customize this variable.
