Add help.autocorrect to enable/disable autocorrecting
It is off(0) by default, to avoid scaring people unless they asked to. If set to a non-0 value, wait for that amount of deciseconds before running the corrected command. Suggested by Junio, so he has a chance to hit Ctrl-C. Signed-off-by: Alex Riesen <raa.lkml@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
