Cannot use multiple @raise on a single Function

If you set multiple @raise such as

--- Some Function
-- @return something
-- @raise error 1 that can be thrown
-- @raise error 2 that can be thrown
function _M.someFunction()
...
end

You get

For those new to this tool, one workaround for multiple raises (and, I presume, multiples of other singleton tags) is to use a single @raise tag but use markdown formatting to clearly show the separate errors.

For example, format the original example above as a list by altering it to:

--- Some Function
-- @return something
-- @raise * error 1 that can be thrown
-- * error 2 that can be thrown

And make sure to process the documentation as markdown by using the -f command line option to specify a markdown processor. For example:

ldoc -f markdown ./

Other possible markdown processors are plain and discount. (See the ldoc documentation for more details.)

Still can replicate this in the latest version.

Looks like this is still around in v1.5.0 too. Anybody want to tackle it?
