Subject: [PATCH] Fix gitmkdtemp: correct test for mktemp() return value
In gitmkdtemp, the return value of mktemp is not tested correctly.
mktemp() always returns its 'template' argument, even upon failre.
Upon failure, mktemp sets template to be an empty string: its first character is '\0'.
This patch ensures the return value of mktemp is correctly tested by dereferencing the pointer returned by it.
