Interactive rebase seems to have broken

[York Zhao]

Hi,

I just pulled the the latest version "5ed79cb" and found that the
interactive rebase is not working anymore. Whenever I tried I get this
error:

$ git --no-pager rebase -i 23fcb3f^
/libexec/git-core/git-rebase--interactive: line 189: -s: command not
found Could not execute editor git exited abnormally with code 1.

Steps to reproduce:

1. M-x magit-status
2. Type "ll"
3. Move to somewhere that I want to rebase from
4. Type "E"
5. The above error shows up


Thanks,
York
