commit ae47a154ae7d4ad403ee1590a0a7f3c94293cf25
Author: G. Branden Robinson <[email protected]>
AuthorDate: Sun Dec 7 10:28:57 2025 -0600
tmac/ja.tmac: Fix Savannah #67757 (1/2).
* tmac/ja.tmac: Correct apparently mistaken character flags for
`[CJKpostpunct]` class from "266" to "256". A typo introduced two
spurious flags (2 and 8).
Fixes <https://savannah.gnu.org/bugs/?67757>. Problem appears to date
back to commit 1cb8dd7bde, 13 December 2010. Thanks to Colin Watson for
suggesting a regression test procedure.
Procedure:

(Why stop at ps(1)? Because the formatter aborts due to input stack
exhaustion on that page [but not when formatted in isolation], which
appears to structurally be in the same shape it was 25 years ago, when
its English counterpart was The Worst Man Page Ever...

...and because a 3.5 megabyte sample of man(7) sources seemed "enough".)
