From: Justin Frankel <justin@xxxxxxxxxx>
Add support for merging with ignoring line endings (specifically
--ignore-space-at-eol) when using recursive merging. This is
as a strategy-option, so that you can do:
git merge --strategy-option=ignore-space-at-eol <branch>
and
git rebase --strategy-option=ignore-space-at-eol <branch>
This can be useful for coping with line-ending damage (Xcode 3.1 has a
nasty habit of converting all CRLFs to LFs, and VC6 tends to just use
CRLFs for inserted lines).
The only option I need is ignore-space-at-eol, but while at it,
include the other xdiff whitespace options (ignore-space-change,
ignore-all-space), too.

That's the end of the series. Thoughts (and tests) welcome, as
