Really minor UI bug.
I have a file named nisvc_SitePageIntegration__c.object. If I right-click on the file name in the Solution Explorer, and choose PULL FROM SALESFORCE, the dialog that appears shows the name as nisvcSitePageIntegration_c.object, losing two of the underscores in the name
Each of the screens shown after the pull show the name correctly, it is just this one screen.
Note that "nisvc_" is not a namespace, it is only a prefix on the name of the file
