Problem

Bug

Take this list item, for instance:

- You might want to replace `--strip-unneeded` with `--strip-debug` for
  static libraries, as dh\_strip does.  When stripping static libraries,
  you should also pass `--enable-deterministic-archives` to ensure that
  your package build is reproducible.

Fix (not ideal since escaping underscores is preferred)

The escape character in dh_strip does not escape the underscore like I would expect.

I had to use an in-line code block to get around this, as in dh_strip:

- You might want to replace `--strip-unneeded` with `--strip-debug` for
  static libraries, as `dh_strip` does.  When stripping static libraries,
  you should also pass `--enable-deterministic-archives` to ensure that
