[PATCH v6 0/2] Honor .gitattributes with rebase --am

This series makes rebase --am honor the .gitattributes file for subsequent patches when a patch changes it.

Changes from v5:
* Avoid leaking memory from already parsed filter rules.

Changes from v4:
* Wrap lines in apply.c.
* Handle merge and conflict-marker-size attributes.
* Add tests for am and am -3 in addition to rebase.

Changes from v3:
* Check for both addition and removal of .gitattributes files.
* Switch from "test_config" to "git config".

Changes from v2:
* Rename has_path_suffix to ends_with_path_components.

Changes from v1:
* Add has_path_suffix in a separate commit.

  path: add a function to check for path suffix
  am: reload .gitattributes after patching it
