Indent on continuation is eaten by formatter

[jwhonce]

I would prefer indentation on continued lines

git fetch --prune upstream \
      && git merge upstream/$branch \
      && git push origin $branch 

currently becomes:

git fetch --prune upstream \
&& git merge upstream/$branch \
&& git push origin $branch

Even a markers for copy block to output would be better.

It would be great if there was a flag to toggle this behaviour. I just ran beautysh on a large infrastructure codebase that makes use of shellcheck, 95% of the changes are this. Would prefer not to have to use markers.
