Fix issue with (nested) definition lists in lib/Pod/Html.pm
|
|
- <dt> tags are not closed
|
|
- generated code contains spurious </li> closing tags
|
|
- when other (definition) lists are nested in a definition list, the
|
|
indentation of sublevels gets messed up because of incorrect
|
|
placement of <dt> tags
|
|
