git am and CRLF files

Hi there. I have:

$ git version git version 1.6.5.1.1367.gcd48

$ git config --get core.autocrlf false

A repository with some UNIX (LF) and some Windows (CRLF) files. (and no: I will not change the files. My editors handle CRLF and LF correctly)

My problem:

'git am' can't handle changes in CRLF files because the patch gets converted (by git mailsplit) to contain only LF.

Which is wrong IMHO.

git-am on my msysgit version looks like this (lines: 214++)

<---------->
split_patches () {
	case "$patch_format" in
	mbox)
		case "$rebasing" in
		'')
			keep_cr= ;;
		?*)
			keep_cr=--keep-cr ;;
		esac
		git mailsplit -d"$prec" -o"$dotest" -b $keep_cr -- "$@" > "$dotest/last" ||
		clean_abort
		;;
<---------->

The '--keep-cr' flags is passed to git mailsplit when git am is in 'rebasing' mode. By looking through git-am I found that I can pass "--rebasing" to git am to get my patch applied correctly. But why is git am behaving that way ?

Puzzled,

Stefan
