[PATCH] [Babel] Add line number to "Processing code block..." message

["Sebastien Vauban" <sva-news-D0wtAvR13HarG/iDocfnWg@public.gmane.org>]

Hello,

Here is a small patch to improve the messages displayed by Org Babel when
processing code blocks: now, you get the line number added to the output, so
that you can easily find afterward which block had problems, if such things
were reported in the *Messages* buffer.

Best regards,
  Seb
