Lists of Inline and Block elements can now be filtered via `Inlines` and
`Blocks` functions, respectively. This is helpful if a filter conversion
depends on the order of elements rather than a single element.
For example, the following filter can be used to remove all spaces
before a citation:
function isSpaceBeforeCite (spc, cite)
return spc and spc.t == 'Space'
and cite and cite.t == 'Cite'
end
function Inlines (inlines)
for i = #inlines-1,1,-1 do
if isSpaceBeforeCite(inlines[i], inlines[i+1]) then
inlines:remove(i)
end
end
return inlines
end
