 102 \r
 103 It looks like this is possible, as Suvayu Ali mentioned too.  An\r
 104 improvement to his example is also mentioned in the manual at\r
 105   http://www.mutt.org/doc/devel/manual.html#set-myvar\r
 106 You can defer evaluation of the variables until runtime by prefixing\r
 107 them with \$.\r
 108 \r
 109 Here are some proposed improved macros.  (I'll attach a patch file in\r
 110 another email.)  Despite my earlier warning about not line-breaking\r
 111 macros, these are getting a bit unreadable.  We may want to see\r
 112 if/where we can safely line-break them.\r
