Traditional roff has two registers for horizontal adjustment:
One to store the current current adjustment mode (left, right,
both, center) and one to switch adjustment on and off altogether
without changing the mode. When adjustment is off, formatting
is the same as in "left" mode. When filling is off, adjustment
is considered temporarily off as well. The requests are:
.ad l \" switch mode to left
.ad r \" switch mode to right
.ad b \" switch mode to both
.ad c \" switch mode to center
.na \" switch adjustment off
.ad \" re-enable adjustment
Mandoc only supports the left mode, .ad and .na are ignored.
The patch changes groff to treat all of these commands as .na.

To leave mdoc.local untouched such that it can be used for
site-specific tweaks. Buts that's not really important,
and i'm not feeling strongly about it.
Yours,
