Thanks, but:
This fix wouldn't work if the first argument was itself a function
with multiple arguments.
And this is whitespace formatted incorrectly.
It:
o needs a space after if
o needs a space after the comma in the fix
o needs to use the appropriate amount and tabs for indentation
o needs alignment to open parentheses
o the backslashes are not required in the fix block
Do you want me to push what I wrote in the link below?
