From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= <u.kleine-koenig@pengutronix.de>

Subject: [PATCH 1/2] rev-parse: fix --parse-opt --keep-dashdash
--stop-at-non-option
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The ?: operator has a lower priority than |, so the implicit associativity
made the 6th argument of parse_options be PARSE_OPT_KEEP_DASHDASH if
keep_dashdash was true discarding PARSE_OPT_STOP_AT_NON_OPTION and
PARSE_OPT_SHELL_EVAL.

Subject: [PATCH 2/2] Check size of path buffer before writing into it
This prevents a buffer overrun that could otherwise be triggered by
creating a file called '.git' with contents
gitdir: (something really long)
