Integrated Jira Task Lookup in Commit Message

At the moment its always a bit of a pain to try to remember your jira task number to link your commit to a task. It would be great if you use similar syntax to Jira's @ mention system to initialize a search. For example

1. Select Commit and select the Commit message field
2. Type a basic message like "Fixed the issue relating to task "
3. then enter the key that triggers the lookup, something like "[" or even jira's "@" which initialises a jira search box in the place of the cursor.
4. Search for something like "My task title".
5. In a list of top matches select down to the task you want to link to
6. Hit enter

Source tree should add to the commit message the jira task id and anything else in needs to link to. for example

"Fixed the issue relating to task JIR-395"
