hello,

it seems that in case the second line of a commit message is not empty,
then git am strips newlines from the commit message. is this expected?

vmiklos@gaia:~/git/t$ git init
Initialized empty Git repository in .git/
vmiklos@gaia:~/git/t$ echo foo > foo.c
vmiklos@gaia:~/git/t$ git add foo.c

vmiklos@gaia:~/git/t$ git commit -a
< here is insert "-foo\n-bar\n-baz" >

    - foo - bar - baz

of maybe the solution would be that git format-patch inserts two
newlines after the subject - even if the second line would not empty
originally.

thanks,
