However I still think it's worth reporting.
I don't think this has changed recently. The manual currently says "The comment should contain a comparison operator, whitespace and a valid version number." In 2.15.0 it was less explicit, but the example contained a space. It may be that some code path worked before more or less by accident, because in December changes were made to the parsing to avoid a tricky reentrancy problem, but I don't think it has ever been documented to work without whitespace.
I can't think of the reason white space was required, but the code does explicitly look for it, so I'd be reluctant to change it.
