「if + comment(!) + label(!!) + one statement」 ← shouldn’t that get braces, style(9)?
fix here string parsing problem found by Stéphane Chazelas
OpenBSD RCSID merge, and logical follow one change:
handle unknown bases as ksh93 does: larger downgrade to 10
(although our max will stay 36, as ksh93 doesn’t have upper/lowecase)
and smaller downgrade for typeset -i, but not for arithmetics
oksh sync RCSIDs only:
• expr.c long done already
• mksh.1 does not apply to us (no character classes)
