[PATCH] Work around sed portability issue in t8006-blame-textconv

From: Ben Walton <bwalton@artsci.utoronto.ca>

Message-ID: <1325339068-6063-1-git-send-email-bwalton@artsci.utoronto.ca>

In test 'blame --textconv with local changes' of t8006-blame-textconv, using /usr/xpg4/bin/sed on Solaris as set by SANE_TOOL_PATH, an additional newline was added to the output from the 'helper' script driven by git attributes.

This was noted by sed with a message such as: sed: Missing newline at end of file zero.bin.

In turn, this was triggering a fatal error from git blame: fatal: unable to read files to diff

The git blame --textconv stdout was empty as a result of the error condition above. This caused the test to fail because the output value differed from the expected result.

Use perl -p -e instead of sed -e to work around this portability issue as it will not insert the newline. This allows the git blame call to complete at which point the output comparison is successful.
