This is problematic: It changes the indentation behavior of the global
functions, depending on whether "rx.el" has been loaded.  Multiline
calls of `=' or `>=' might be rare, but multiline `rx' subexps are rare
as well.

Can we delay such changes until we have some kind of context sensitive
indentation algorithm for Elisp?

TIA,

Michael.
