Subject: t0020: add test for auto-crlf
X-Git-Tag: v1.5.1-rc1~258^2~1
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=634ede32ae7d4c76e96e88f9cd5c1b3a70ea08ac;p=git.git

t0020: add test for auto-crlf

This tests lowlevel of update/checkout codepaths and some patch
application.  Currently, variants of "git apply" that look at
the working tree files does not work, so it does not test the
patch application without parameter and with --index parameter
when autocrlf is set to produce CRLF files.

We should add test for diff generation too.
