Fit to Plan 9's ANSI/POSIX compatibility layer
tr(1) of ANSI/POSIX environment, aka APE, don't support \n literal. It's handles only octal(\ooo) or hexadecimal(\xhhhh) numbers. And its sed(1)'s label is limited to maximum seven characters. Therefore I replaced some labels to drop a character. * close -> cl * continue -> cont (cnt is used for count) * line -> ln * hered -> hdoc * shell -> sh * string -> str Signed-off-by: Kyohei Kadota <lufia@lufia.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
