Subject: t6042: Add a testcase where git deletes an untracked file
X-Git-Tag: v1.7.7-rc1~28^2~56
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=695576fddd039b2fdc3cad52bbaab4d89e27b71c;p=git.git

t6042: Add a testcase where git deletes an untracked file

Current git will nuke an untracked file during a rename/delete conflict if
(a) there is an untracked file whose name matches the source of a rename
and (b) the merge is done in a certain direction.  Add a simple testcase
demonstrating this bug.
