The zypper man page (`man zypper`) contains several formatting errors: Starting
at the description of the "install (in)" command various '+' and occasional '-'
signs are spread in the text without any obvious reason.
Later on (starting in the "-t, --type" option of "in") the man page contains
whole passages incorrectly printed in bold or underlined.

Looking at the spec file it seems this only happens when the man page was
generated using Ruby's asciidoctor, pages created with asciidoc seem to look
correct.
