just to give the general idea and not claiming that the Ignite people do 
it like that.. normally what you do is the following:

1) create a bug-fix branch based on master
2) commit your changes to the bug-fix branch
3) test/verify by the community and CI
4) merge bug-fix branch to master
5) delete bug-fix branch

In this process there is no loss of commits, the information stays in 
the master branch. In git you normally keep only the branches people 
work on, or you use tags.

Step 4 can be done in multiple ways. Of course normally the first choice 
is the git based merge, but you can also work with a patch set (the 
author/date information is not lost by this) or cherry-pick (which is 
like duplicating the commit on another branch). branching off and 
merging again, can be seen in tools like for example gitk or with for 
example "git log --graph". Examples can for example be seen on 
using different tools. Noteworthy here is that normal commits are 
handled similar to branches. In other words, git does not really know a 
concept like a branch as it was with svn/cvs. Instead it is an 
elementary part of the system, that every commit has a parent and 
possibly a child and from this results a commit graph. A branch is only 
a commit noted as head. Deleting a branch thus means only to delete that 
meta information. And unlike CVS/SVN git is based on a database. Even if 
you do "git rm" to delete a file, it is still in the database and not 
removed from history.
