Re: [PATCH] git-p4: changelist template with p4 -G change -o

[miguel torroja <miguel.torroja@gmail.com>]

Hi Lars/Luke,

I tried a first test extending t9807-git-p4-submit.sh. I set this p4
trigger: 'p4test command pre-user-change "echo verbose trigger" '. I'm
able to reproduce the issue I wanted to fix. However I found yet
another issue, in this case when reading the result from
p4_read_pipe_lines (in function p4ChangesForPaths), the
pre-user-change is triggered with any "p4 change" and "p4 changes"
command (the p4 server we have in production, only shows "extra"
messages with p4 change).
   I'll collapse in one single commit the fix for p4 change/p4 changes
and the new test.

Thanks,

Miguel
