Literate patch problems

[Jean-Marc Lasgouttes]

Hello,

Kayvan, I have quesyions about the build-listerror script:

- why use vncserver (which many people will not have)? I though that
  Xvfb could be used to run LyX without any GUI in any case.

- are you sure that your script is portable? I do not think that all
  bourne shells support functions.
