Hi Paul, I mentioned in an earlier patch submission that to add collision check of commandchars in fcvextract.pl was on my to-do list. It turned out that fcvextract.pl is already complicated and I changed my mind to add a separate script to check .fcv files for the collisions. Patch #1 adds the script as utilities/checkfcv.pl. Patch #2 adds the invocations of the script in Makefile. It also suppresses the echo of commands in the recipes. Patch #3 fixes a couple of collisions detected by the script. The two collisions were made by myself. This automatic check looks promising to me.
