errors in pod

[Olivier Sallou]

Hi,
in v2.42, I found several errors in POD structure, preventing the pod2man transformation, plus a few typo errors.
Follows a patch to fix those errors.
I am not a pod expert, fixes remove errors but you may check what is best appropriate.

A pull request via git would make it easiest to incorporate your changes. If not I expect someone can make these fixes.
