The reason is that without a letter, the number can potentially be interpreted as a decimal numeric string, which it is not. AFAIK there is no code directly in Fossil which would treat it as such, but copy/pasting the hash, as well as using such a hash in JS via the JSON API, could very well cause misinterpretation of 1234567890 as a decimal number. Ensuring at least one of [a-f] eliminates that problem. > and makes parsing by scripts slightly more complicated. i would argue the opposite - it hardens them against misinterpretation. -- ----- stephan beal http://wanderinghorse.net/home/stephan/ http://gplus.to/sgbeal "Freedom is sloppy.
