Add filename and current function to placeholders?

[dajoho]

I think it would be great if we could add extra information to the JIRA Tickets, like the current file name, or function. (This could be done with placeholders).

e.g.

function whatever()
{
      // TODO implement sorting here
}

... would create a JIRA Issue like this:
// TODO BSP-1 crazyexample.php - whatever() - implement sorting here.

The comment replace could look like this:

/* TODO {Key} - {Filename} - {Function} - {Summary} */

Is this possible already? What do you think of the idea?
