Description

I propose the addition of Text.PrettyPrint?.HughesPJ.zeroText :: String -> Doc

This function is essential for outputting HTML which contains textual markup which occupies no space. For an example of it's use see:  http://darcs.haskell.org/yhc/src/libraries/core/Yhc/Core/Html.hs

One week for discussion

Discussion stopped ages ago, but given the base split was going on at the time, I held off finishing this off. The final concensus was:

Yes, but call it zeroWidthText.

Various people admitted to including it in their pretty-printing libraries, or cloning other libraries.

  * Adds a `zeroWidthText' primitive to the library, in order to create text
  which occupies no space (e.g. html or latex tags).
