protoc supports negative numbers for default values

Type the following message into any proto file created by the plugin.

message request {
    optional sint32 content_length = 1 [default = -1];
}

The plugin should see this as a valid protobuf message.
The plugin reports the line with the "-1" as being in error.
Protoc processed the message as expected.

What version of the product are you using? On what operating system?

I am using Netbeans 6.7.1 and ProtobufEditor 1.0.3. 
Problem occurs on both ubuntu 9.04 and winxp.

Please provide any additional information below.
I reviewed the nbs file from svn and see the problem is in the parsing. I 
do not know this parsing technology well enough to create the rules for 
parsing the default value based on the defined type as is done in 
parser.cc.
