Redmine

When a new issue is created, currently control returns to the issue index list. You then need to reselect it from the
list to do any further edits. If you did not actually assign the issue to yourself in the process of creating it, the
issue is lost from your view of the index page, making it difficult to know what it's new number is too.

This patch changes where control goes after creating the new issue. It redirects back to the issue display page, so
that it can be further updated, time logged etc. This way it is also consistent with what happens after completing
an edit to an issue.
