During "git p4 clone" if p4 process returns an error from the server, it will store the message in the 'err' variable. Then it will send a text command "die-now" to git-fast-import. However, git-fast-import raises an exception: "fatal: Unsupported command: die-now" and err is never displayed. This patch ensures that err is shown to the end user.

 | 
						|
    The `p4-pre-submit` hook is executed if it exists and is executable. It
 | 
						|
    can be bypassed with the `--no-verify` command line option. The hook takes
 | 
						|
    no parameters and nothing from standard input. Exiting with a non-zero status
 | 
						|
    from this script prevents `git-p4 submit` from launching.
 | 
						|
 | 
						|
    One usage scenario is to run unit tests in the hook.
 | 
						|
 | 
						|
    The `p4-prepare-changelist` hook is executed right after preparing the default
 | 
						|
    changelist message and before the editor is started. It takes one parameter,
 | 
						|
    the name of the file that contains the changelist text. Exiting with a non-zero
 | 
						|
    status from the script will abort the process.
 | 
						|
 | 
						|
    The purpose of the hook is to edit the message file in place, and it is not
 | 
						|
    supressed by the `--no-verify` option. This hook is called even if
 | 
						|
    `--prepare-p4-only` is set.
 | 
						|
 | 
						|
    The `p4-changelist` hook is executed after the changelist message has been
 | 
						|
    edited by the user. It can be bypassed with the `--no-verify` option. It
 | 
						|
    takes a single parameter, the name of the file that holds the proposed
 | 
						|
    changelist text. Exiting with a non-zero status causes the command to abort.
 | 
						|
 | 
						|
    The hook is allowed to edit the changelist file and can be used to normalize
 | 
						|
    the text into some project standard format. It can also be used to refuse the
 | 
						|
    Submit after inspect the message file.
 | 
						|
 | 
						|
    The `p4-post-changelist` hook is invoked after the submit has successfully
 | 
						|
    occurred in P4. It takes no parameters and is meant primarily for notification
 | 
						|
    and cannot affect the outcome of the git p4 submit action.
