commit c7289acc12e62fc3386125b78d9bd0ef52409a22

[man]: Add bespoke handling of `lbp` device.
* tmac/an.tmac (EX): Refactor, using new register `an*unmap-fonts` to
keep track of whether we're remapping fonts instead of switching
families. Like TeX DVI, the LBP output device lacks a (complete)
monospaced font family. In EX/EE examples on that device, remap the
bold-italic face to italics.
(EE): Revert remappings and remove `an*unmap-fonts` register.
Prompted by discussion with pandoc developers at
<https://github.com/jgm/pandoc/issues/9020>.
