regex_side_effect_conversion_impl
=================================

Similar to regex\_conversion\_impl, except the output is not determined as the
final state of the (edited) input buffer.  The output starts out empty and
each rule has a "side effect" that is appended to the output when that rule
is applied.  This is useful when the input and output have similar character
spaces and structure.

add
===

	some_rc add search replace append

Appends a new rule to the list in `some_rc`; the new rule has `search` as
the element sought, `replace` as the element that replaces it and `append`
as the side effect on the output.  `search` may contain regular expression
elements (as implemented by boost) and `replace` and `append` may contain
elements like `\1` to refer to parenthesised expressions in `search`.

remove
======

	some_rc remove search replace append

Removes the rule mapping `search` to `replace` with side effect `append` in
the rule list of `some_rc`.

list
====

	some_rc list

Emit the list of rules for `some_rc`.

set_restart
===========

	some_rc set_restart 0

Change the rule search to examine all rules before starting again at the 
beginning of the list of rules

	some_rc set_restart 2

Change the rules search to examine each rule exactly once.

	some_rc set_restart 1

Reinstate the default behaviour of starting the rule search at the 
beginning of the rule list anew after a successful match.
