In vtodos Zanshin's task description is decomposed into a SUMMARY and a DESCRIPTION. Because zanshin itself does not explicitly differentiate between these concepts, when adding a task to Zanshin, I separate with a white line the SUMMARY and DESCRIPTION (that looks better visually). However, then a '\n' is inserted in the vtodo item at the start of the DESCRIPTION field. It should not be there. It can be easily stripped, I guess.

I am talking here about vtodos, because that is my use case, but this report is equally valid for interoperability with Kontact's task manager, which is heavily inspired by vtodo functionality. There, in the DESCRIPTION field also a spurious blank line is added. 

In Zanshin itself the first line of the unified SUMMAR+DESCRIPTION box is used as a SUMMARY/Title for purposes of listing the task in the task list. So perhaps  this first line should also be differentiated in the unified text box, e.g., by italicizing it, or adding some whitespace or a line below it, or yet something else.
