on a same line only the first undocumented variable is indicated

Minor issue. Also when a comment is finally added then the variables 1..$ are not detected at all.

e.g

int a,b ; // variable a is not ....

/// some DDOC
int a,b ; // no message for b

[WebFreak001]

/// some DDOC
int a, b;

results in documentation for a and b though and not just for a, so the second behavior is correct
