Subject: Fix empty arguments on launcher rerun after git pull
X-Git-Url: https://vcs.fsf.org/?a=commitdiff_plain;h=8100fab05d12d56c8204b467f4b68811b8c0c796;p=discourse_docker.git

Fix empty arguments on launcher rerun after git pull

Variable $@ cannot be used to get arguments for launcher rerun, because the usage of the shift (line 44) command has removed all entries from $@. Instead $BASH_ARGV can be used, but $BASH_ARGV contains arguments in reversed order.
