[PATCH 1/1] quote: quote space

[Han Young <hanyang.tony@bytedance.com>]

`git_header_name()` in apply.c uses space as separator between the preimage and postimage pathname, filename with space in them normally won't cause apply to fail because `git_header_name()` isn't using simple split. However, if the pathname has a directory whose name ending with space will lead to `skip_tree_prefix()` mistake the path as an absolute path, and git am fails with

	error: git diff header lacks filename information when removing 1 leading pathname component

The simplest fix to this edge case is to quote every path with space, even if the space is not at directory name end.
