[PATCH v6 3/3] Don't expand CRLFs when normalizing text during merge

From

Message-ID
<6a8530fa3cba7cbc14882a9f5979d13452ab52b5.1278093311.git.eyvind.bernhardsen@gmail.com>
In-Reply-To
<cover.1278093311.git.eyvind.bernhardsen@gmail.com>

Disable CRLF expansion when convert_to_working_tree() is called from normalize_buffer(). This improves performance when merging branches with conflicting line endings when core.eol=crlf or core.autocrlf=true by making the normalization act as if core.eol=lf.
