What is "git patch"? An alias for "format-patch?".

Can you be more specific about the input you're feeding to git and the
output you're seeing?
For instance, if I do:
git init
echo content >file
git add file
git commit -m "$(perl -e 'print join(" ", 1..100)')"
I get a commit message with one long unwrapped line, which I can view
via git-log, etc. Now if I try to run filter-branch on that:
git filter-branch --commit-filter '
input=$(cat)
{
echo "===================="
echo $input
echo "===================="
} >>/tmp/paging_bug.txt
git commit-tree "$@" -m "$input"
'
then the commit remains unchanged, and paging_bug shows one long line.
What am I missing?
(I wondered at first if the extra "cat" and "-m" could be messing up
whitespace for you, but it should not, as the quoting around "$input"
should preserve things like newlines. And anyway, the bug in that case
would be the _opposite_; I'd expect it to stuff everything onto a single
line rather than breaking lines).
