    launch_editor(): indicate that Git waits for user input · abfb04d0
    Lars Schneider authored
    When a graphical GIT_EDITOR is spawned by a Git command that opens
    and waits for user input (e.g. "git rebase -i"), then the editor window
    might be obscured by other windows. The user might be left staring at
    the original Git terminal window without even realizing that s/he needs
    to interact with another window before Git can proceed. To this user Git
    appears hanging.
    
    Print a message that Git is waiting for editor input in the original
    terminal and get rid of it when the editor returns, if the terminal
    supports erasing the last line.  Also, make sure that our message is
    terminated with a whitespace so that any message the editor may show
    upon starting up will be kept separate from our message.
    
    Power users might not want to see this message or their editor might
    already print such a message (e.g. emacsclient). Allow these users to
    suppress the message by disabling the "advice.waitingForEditor" config.
    
    The standard advise() function is not used here as it would always add
    a newline which would make deleting the message harder.
