/*
* Fix CTRL macros
*
* Basically, what is supposed to be happening is that every
* _invocation_ of the "_CTRL()" or "CTRL()" macros is supposed to have
* its argument inserted into single quotes. We _must_ do this because
* ANSI macro substitution rules prohibit looking inside quoted strings
* for the substitution names. A side effect is that the quotes are
* inserted in the definitions of those macros as well. So, the last
* three sed expressions are supposed to clean up the definitions, as
* long as those definitions are using "c", "g" or "x" as the macro
* argument :). Yuck.
