git commit --cleanup and templates

Hi,

when I recently for the first time used commit templates, I was surprised to see that git by default strips leading empty lines that I deliberately added to the template file when opening the template in the editor. I understand that I could use a different cleanup mode, but in fact I *want* git to clean everything, but only *after* I finished editing the commit message, not already when opening the editor.

Before submitting a patch, I'd like to hear what other people think about this, or whether I'm overseeing something.

Thanks.
