Re: [Nmh-workers] proposed patch for shell metacharacter failure in nmh-1.7

I really think to be safe we should simply
replace any shell metacharacters for those things,

I'm not sure that could be done completely safely.  See below about not
using /bin/sh -c.

Our official list of shell metacharacters in argsplit() is:

#define METACHARS       "$&*(){}[]'\";\\|?<>~`\n"

It seems like replacing all of those for any MIME parameter we encounter
would make sense, and would be safe?
