tex-bxjaprnind{,-doc}: Add version 0.3b

From Atsushi Toyokura in pkgsrc-wip

In Japanese typesetting, opening parentheses placed at the
beginning of paragraphs or lines are treated specially; for
example, while the paragraph indent before normal kanji
characters is 1em, the indent before parentheses can be 0.5em,
1em or 1.5em deoending on the local rule in effect.
