Please describe the problem.

I am importing a lot of old documents into my annex. Some of these old files apparently have newlines in their filename. A run of git annex import aborts when it encounters such a file; the file is moved to the annex, but it is left unstaged.

What steps will reproduce the problem?

bram@durian% mkdir annex
bram@durian% cd annex
bram@durian% git init
Initialized empty Git repository in /home/bram/tmp/t/annex/.git/
bram@durian% git annex init
init  ok
(Recording state in git...)
bram@durian% echo foo > ../$'foo\nbar'
bram@durian% ls -lb ..
