hard to tell, it has been using short in the idl since at least 2000-11-06

so... I will keep it functionally broken by downcasting to sal_In16
and keep the api getting and return short for now.
and mark if as "FIXME API" so that we turn that to sal_Int32 if/when
we choose to do a abi incompatible change

Clearly there are no current use where max text length is bigger than
32767... so keeping it a short for now would not break anything more
than it already is :-)
but one of the point of OUString is to left the 64K limit... so at
some point this need to be adjusted too....
