Patch cleanup for merge

After reviewing the gitignore support with Vicent, we came up
with a list of minor cleanups to prepare for merge, including:

* checking git_repository_config error returns
* renaming git_ignore_is_ignored and moving to status.h
* fixing next_line skipping to include \r skips
* commenting on where ignores are and are not included
