[Pkg-emacsen-addons] Bug#841524: Depend or Suggest markdown package for preview to work

[Tommi Vainikainen]

Package: elpa-markdown-mode
Version: 2.1-1
Severity: normal

elpa-markdown-mode should either Depend or Suggest markdown package so
that markdown-preview function would work correctly. If not Depends,
then it would be also nice to give nice error message about missing
command instead of preview page in a browser containing "/bin/bash:
markdown: command not found".
