Yes - if you apply the way "rebase -i" works to multiple commits you can 
end up with a message template that has a screen full of commented lines 
between uncommitted parts of the message. See the example below from 
earlier in the thread. It is not so much of a problem in "rebase -i" 
because it only fixes up a single commit at a time so all the commented 
messages end up at the top of the buffer and at worst you have a few "# 
fixup! ..." or "# squash! ..." lines mixed in with the uncommitted text.

     # This is the combination of 4 commits
     # This is the first commit message
     Base subject

     Base body

     # This is the second commit message
     # Another subject

     # Another body

     # This is the third commit message
     # fixup! Base subject

     # This is the fourth commit message
     # amend! Another subject
     A better subject

     A better body

Thanks
