Basically I want to use the JIRA bug number for both SourceLinks and Hashtags. Unfortunately, hashtags only recognize XXXnnnn while Sourcelinks can recognize XXX-nnnn but not XXXnnnn.
case=90329 is partially implemented in build 2073 as an optional enhancement. In 2073, the registry value named HashtagsAllowHyphens defaults to 00. Change it to 01 for VA to display hashtags with dash/hyphen in the hashtags toolwindow.
