gitloggrep broken - possibly after Python 3?

[pfuntner]

It looks as though this tool is broken, possibly after the Python 3 switch:

$ gitloggrep -i wip
fatal: ambiguous argument 'wip': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
Traceback (most recent call last):
  File "/home/mrbruno/bin/gitloggrep", line 21, in <module>
    stderr = stderr.decode('utf-8')
AttributeError: 'NoneType' object has no attribute 'decode'
$ 

I kind of hate the name too. git-log-grep might be better?
