It would be great if we can have this feature. Like we have a great feature of referencing trackers with XXX #NNN format. Its great and it would be better it has a way to auto populate commit message to task follow up.
Like for example,
I have done some commit with message :
bug #256 #comment exception while getting user information is fixed, it was due to incorrect if statement.
or it could be :
story #658 #comment implemented ..... but still validations are need to corrected
those texts will be added as follow-ups automatically within referenced tracker id. It would be a very nice feature and trackers will have more transparency/interlinking with the code commits.
