Dollar sign issues

[jeff]

I just did some testing with latest from CVS and discovered the
following problems

1) The basic $$ problem: (I have mentioned this before)

          #set ( $a = "2.99" )

          Today's special sale price: $$a

renders as 
          Today's special sale price: $$a


2) The ${ problem:

        ${
        $a{
        $$a{
        \${

Any of the above cause an exception that looks something like this:
    org.apache.velocity.exception.ParseErrorException: Encountered "\r\n" at line 5, 
column 12.
    Was expecting:
        <IDENTIFIER> ...
    
            at org.apache.velocity.Template.process(Template.java:169)
            at 
org.apache.velocity.runtime.resource.ResourceManager.getResource(ResourceManager.java:336)
            at org.apache.velocity.runtime.Runtime.getTemplate(Runtime.java:666)

3) The disappearing } problem:

         #set( $z = "foo" )

         $z}

renders as

         foo


I have workarounds for all these but I thought I should report them.
