I am working on a project which has the root directory constructed with 
a leading space. i.e. ./ dir/. "read" skips the leading space char, and 
ends up with an incorrect filename, which can then not be found. Setting 
IFS=\n solves this problem.

Thanks to Mikachu and Tv on #git for assistance and suggestions.

Unfortunately, Thunderbird is not very easy to convince not to mangle 
patches, so I am attaching the patch as well. Sorry.
