[PATCHv4 0/4] Using git-mailsplit in mixed line ending environment

["Stefan-W. Hahn" <stefan.hahn@s-hahn.de>]

Hello,

I'm using git in environments with files having dos or unix line
ending. I apply patches using 'git format-patch ... | git am ...'.
A change in git-mailsplit in commit c2ca1d79 introduced a change in
the default behaviour of git-mailsplit when splitting mbox patches. It
makes dos line endings to unix line endings. With this behaviour it is
impossible to apply patches.

The following patches introduce the '--kepp-cr', '--no-keep-cr'
parameter to git-am an an additional possibility to set '--keep-cr'
via configuration for git-am. Also I added missing description for
'--keep-cr' of git-mailsplit.

Second round:
I changed 'mailsplit.keep-cr' to 'mailsplit.keepcr' as suggested by Jakub
and comment in the testcase.

Third round:
I moved configuration 'mailsplit.keepcr' to 'am.keepcr' because
git-mailsplit can be used outside a git repository (thx Junio).

Fourth round:
I considered the replies from Junio and split up the patch introducing 
configuration am.keepcr in two. I introduced an '--no-keep-cr' to overwrite
configuration. I removed git-mailsplit tests from the test suite, they only 
showed the behaviour when using dos line ending.
I added some tests to show the correct behaviour in different situations
using the new parameters and configuration.
