We have too few dashes under "Examples", which causes Asciidoctor to not
pick it up as a section header. Instead, it thinks we are starting a
code listing block, which ends up containing the remainder of the
document. The result is quite ugly.

Make sure we have as many dashes as we have characters in "Examples".
Asciidoc renders identically before and after this patch, both man-page
and html.
