[PATCH 04/10] shell helpers usage: always send help to stderr

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



`git submodule asdf` would trigger displaying the usage of the submodule
command on stderr, however `git submodule -h` would display the usage on
stdout. Unify displaying help for shell commands on stderr.
