Also "+" is a metacharacter in grep and awk. "-" is too but only if it
appears within brackets. Can the metacharacter be escaped?
Just a quick thought on a different tack. Is it anything to do with
"+<number>" being treated as a number rather than a string? Does
inserting an "@" before the path help?
