[bug#53394] [PATCH] gnu: Openbox: Make compatible with Python 3.

[bug#53394] [PATCH] gnu: Openbox: Make compatible with Python 3.

[Leo Famulari]

As the patch file says, Openbox seems abandoned upstream. So, as Python 2 is
phased out, we can either use a patch like this, or remove Openbox.

I rebuilt all affected packages on x86_64-linux, and there were no new build
failures, only the same failures as before this patch:

kdepim-runtime-20.04.1
kmail-20.04.1
akregator-20.04.1
scorep-openmpi-3.1
smb4k-3.0.6

* gnu/packages/patches/openbox-python-3-compatibility.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/openbox.scm (openbox)[source]: Use it.

I noticed that with 'python' the shebang in libexec/openbox-xdg-
autostart becomes '#!/usr/bin/env python' while with python-wrapper it
changes to the store path.

I also 'cat' that file and the code is still in Python 2. Can you check
this?

openbox.scm is missing the copyright line, and python2-xdg should be
changed to python-xdg. There are trailing whitespaces in the patch.

Leo, Vinicius,

What’s the status of this patch?  Looks like it was almost ready.

Thanks,
