Re: package-vc support for :files keyword

[Adam Porter]

FWIW, it seems like a bit of an anti-pattern for shell commands to be 
part of Elisp packages' recipes.  I can see how it may be necessary for 
certain ones that support external software that may need to build a 
module, etc, but it seems like that sort of thing should be kept to a 
minimum due to, e.g. potential security issues with executing code at 
install time.  Or am I missing something?  :)
