Summary: expr and dollarsign variable tomfoolery

Initial Comment:
If a dollarsign variable like $1 exists in an abstraction (and has a float value assigned) it can be used with impugnity, such as [expr int($1)].  However, if $1 does not exist, as in a newly created patch with <ctrl-n>, [expr int($1)] will not create.  As a workaround, one must appease the expr parser by offering up sacrificial spaces to pad the $1 like so:
[expr int( $1 )]
