[PATCH v6 23/44] builtin/apply: make write_out_one_result() return -1 on error

From: Christian Couder <hidden>
Date: 2016-06-16 02:19:51
Subsystem: the rest · Maintainer: Linus Torvalds

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

To do that in a compatible manner with the rest of the error handling
in "builtin/apply.c", write_out_one_result() should just return what
remove_file() and create_file() are returning instead of calling
exit().
