[PATCH 1/2] dir.c: Make git-status --ignored more consistent
The current behavior of git-status is inconsistent and misleading. Especially when used with --untracked-files=all option:
- files ignored in untracked directories will be missing from status
output.
- untracked files in committed yet ignored directories are also
missing.
- with --untracked-files=normal, untracked directories that contains
only ignored files are dropped too.
Make the behavior more consistent across all possible use cases:
- "--ignored --untracked-files=normal" doesn't show each specific
files but top directory.
Shows untracked directories that only contains ignored files, and
ignored tracked directories with untracked files.
- "--ignored --untracked-files=all" shows all ignored files, either
because it's in an ignored directory (tracked or untracked), or
because the file is explicitly ignored.
