git's --stat output is intended for humans and since v1.7.9.2~13 (2012-02-01) varies by locale. The tests in this script using "apply --stat" are meant to check two things: - how binary file changes are accounted for and printed in git's diffstat format - that "git apply" can parse the various forms of binary diff Split these two kinds of check into separate tests, and use --numstat instead of --stat in the latter. This way, we lose less test coverage when git is being run without writing its output in the C locale (for example because GETTEXT_POISON is enabled) and there are fewer tests to change if the --stat output needs to be tweaked again. While at it, use commands separated by && that read and write to temporary files in place of pipelines so segfaults and other failures in the upstream of the processing pipeline don't get hidden.
