kre e76b58b2db In uses like $(( var )) (un-dollared vars in arithmetic) we allow ... leading whitespace in the value of var (because strtoimax() does) but did not allow trailing whitespace. The effect is that some cases where $(( ${var:-0} )) would work do not work without the $ expansion. Fix that - allow trailing whitespace. However, continue to insist upon at least one digit (a non-null var that contains nothing but whitespace is still an error). Note: posix is not helpful here, it simply requires that the variable contain "a value that forms a valid integer constant" (with an optional + or - sign).		2018-04-21 23:01:29 +00:00
