#9 named return value in tex output only

[Ofer Nave]

If you document a function and use the @return tag to
document the return value, and generate both html and
tex output, you get different results.

In the html output, the entire string after @return is
treated as a description.

But in the tex output, the first word in the line is
treated as the name of the return value, and then the
rest is taken as the description, similar to the
behaviour of the @param tag.
