[PATCH v10 18/40] builtin/apply: change die_on_unsafe_path() to check_unsafe_path()

<20160808210337.5038-1-chriscool@tuxfamily.org>

To libify `git apply` functionality we have to signal errors to the caller instead of die()ing.

To do that in a compatible manner with the rest of the error handling in "builtin/apply.c", die_on_unsafe_path() should return a negative integer instead of calling die(), so while doing that let's change its name to check_unsafe_path().
