Spaces around => in associate

[hr87]

After formatting the white spaces around the => operator in the associate construct were removed. I have all white-space options turned on, and --whitespaces set to 4.

Expected behavior:
Format to: associate(a => b)

Actual behavior
associate(a=>b)

Access operators % in the associate construct are formatted correctly.

fprettify treats the operators = and => in the same way: spaces are inserted around the operators = and => if they do not occur inside delimiters (such as brackets). This rule is necessary to distinguish between assignments a = b where spaces should be inserted and keyword arguments CALL subr(a=b) where no spaces are preferred (in my opinion). I prefer to keep whitespace formatting for operators simple and general and to not parse Fortran-specific syntax.

I completely agree on the behavior for =. But you don't require specific syntax checking, since => always has spaces, however, you can't combine => and = then.

If you would consider adding this, I would take a look and would try to create a patch for this, by adding a new rule for the operator =>. If would be great if you could point me to the right line for the = rule.

Not fixing this would break expected behavior in the associate construct and makes it difficult to read.

Thanks for the suggestion, I took care of it.
