Grass GIS can not install extensions without grass-doc beeing installed

[benste]

Hi there, there seems to be a packaging issue, grass g.extensions does require the docs package to be installed but it is not set as a requirement.

Steps to reproduce the issue
1. install grass
2. open grass (in my case & GUI)
3. quit GUI
4. type g.extensions to open the extensions manager
5. choose to install any extension e.g. v.in.osm
6. click run

following error occurs (sorry for not using pastebin)

g.extension extension=v.in.osm operation=add

grass-core will never depend on grass-dev because that introduces a circular dependency.

grass-core may gain a dependency (Recommends) on grass-doc for g.extensions.

[Bas Couwenberg (sebastic)]

The packaging for the upcoming 7.2.0 release has been updated to make grass-core depend on grass-doc.

@Bas thanks for the quick reaction and applicable changes.
I supose that only some extensions require the dev package to be installed.
If you could check with the version whether osm input filters are installable that would be great.

This bug was fixed in the package grass - 7.2.0-1

---------------
grass (7.2.0-1) unstable; urgency=medium

  * New upstream release.
  * Make grass-core depend on grass-doc, g.extension requires some of its files.
    (LP: #1646812)
  * Drop svn-r69952-dglib-update-to-libavl-2.0.3.patch, included upstream.
  * Update license & copyright for avl.
  * Add patch to fix spelling errors.
  * Add patch to fix hicolor icon name.
  * Move from experimental to unstable.
