A git command that opens an editor to stage or unstage files.
This command represents a faster alternative to git add -i or git gui. It allows you to stage or unstage files from the index in an editor, just like when you perform an interactive rebase.
For example, lets assume you have the following three modified files (git status --short):
M path/to/file1 M another/path/to/file2 M yet/another/path/to/file3
After running git edit-index, an editor will show up with the above output. To stage (add) the first two files, simply change the text to
A path/to/file1 A another/path/to/file2 M yet/another/path/to/file3
The supported statuses are M, A, D, and ?. They allow you to not only stage files but also unstage them, delete them, or revert changes done to them since the last commit.
