Issue-Links from Repository Log to JIRA is sometimes wrong

We're running Stash & JIRA in our Company and usually committing Changes with a JIRA Issues Key within the Commit-Message to display the Issue within the Repository Log view.

However Stash seems to thread anything like "abc-1" or "OPS-665" as a regular JIRA Issue. This however isn't always true as we've done a lot of Commits like "Update Coding Style to be PSR-2". Stash does actually thread "PSR-2" as an Issue and links that to JIRA. There isn't even a project on JIRA which is called "PSR" (and therefor no such Issue Key).

It'd be nice if Stash could fire a Lookup in JIRA if there's a project (or even an issue) before setting such a link on the web. It's not a major Problem, however our Product-Owners/Project-Managers do get confused by this behavior from time to time.
