There is nothing in the diff besides the format number changing from
93 to 95. From what I understand, this is as expected since 93 -> 94
and 94 -> 95 just add new layout tags.
Updating the layouts makes it easier to test master. Otherwise, in
some use cases layout2layout can be run hundreds of times which can
make some things slow (e.g., opening documents or even opening the
advanced find pane).
Includes a fix when wrappers are used with empty paragraphs. The logic is probably wrong if two legit wrapped paragraphs have one empty paragraph in the middle. This is only for slightly convoluted cases... Wrapping decisions should rather be taken for a series of paragraphs at once, but it would be more complex to implement and would only solve very peculiar cases like these ones.
This uses the InsetArgument interface to provide access to a document
part hitherto inaccessible by LyX: the part between \begin and the first
\item in a list (where lengths and counters can be redefined, for
instance).
