But the first command, the one to create the separate debug info file,
is still needed, right?

In any case, we should tell that these commands (or at least the last
one) is only needed for the debug-link method.

"if the signature is present", the "is" part is missing.

This is fine, but there's no need to quote ``debug ID'' every time you
use it. I quoted it only when I used it as a name of a method of
embedding information about the debug file; in other cases I used it
without quotes.

Otherwise, these two patches are okay with me.

Thanks.
