MacOS High Sierra

Standalone code, or other way to reproduce the problem

https://gist.github.com/ssandler/a4b49b290640d92b615f1373c6b0de17

Using the above file, run this command:

hackfmt --in-place --indent-width 8 --tabs --line-width 160 test.php

This only repros if the file starts off with tab indenting to begin with, so make sure that wherever you paste this into, you have tabs in the file.

Actual result

Each time I run hackfmt, it indents part of the docblock by one level.

Expected result

The code should be unchanged by formatting.
