Subject: use -i0 by default but allow TRAIN_PPWDATA_SEL_BIT to override; allow comb-* to try... 
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ijackson/git?a=commitdiff_plain;h=714b372019597c44535edddd3d86175974b4c8c2;p=trains.git

use -i0 by default but allow TRAIN_PPWDATA_SEL_BIT to override; allow comb-* to try out fancy combinations (which are known not to work properly, but hey)
