I'm preparing a PR for a feature I want to add (removing the space requirement between the # and the annotations).

In my local copy I've made the shdoc changes and I'm creating test cases for my "nospace" feature based on the current test cases.

The @std{in,out,err} tests are failing. When I went to look at the shdoc code to figure out why, I see a confusing situation for those annotations. Unlike the other multiline annotations (@description, @example), the @std{in,out,err} annotations have a large and complex set of code for the purpose of tracking indentation. But I can't figure out why--what is the use case for tracking indentation on a multiline @stderr block and not a multiline @example block, for example? Why can't a @stdout block be treated the same as a @description block?
