Effect of newline in macro definition

In the Texinfo manual, under "Macro Details", there is this example:

          @macro linemac
          @cindex whatever @c
          @end macro

It states:

     Without the '@c', there will be a unwanted blank line between the
     '@cindex whatever' and the 'bar' (one newline comes from the macro
     definition, one from after the invocation), causing an unwanted
     paragraph break.

However, I tried it without the @c and didn't get a paragraph break. A
test Texinfo file and the Info output file are attached.

The statement that "one newline comes from the macro definition"
appears to be incorrect. From the "Defining Macros" node in the

    The newline characters after the '@macro' line and before the '@end
    macro' line are ignored, that is, not included in the macro body.

This implies that the last line of a macro body doesn't have a newline
at the end when it is expanded. Hence "@linemac" expands to "@cindex
whatever" without a newline at the end.
