Description of problem:
journalctl would benefit by having a more convenient way to filter by _COMM.  If I want to see a particular python program, I have to use:

  journalctl _COMM=foo

I am proposing a -C option (like ps) which would shorten this to:

  journalctl -C foo

On fedora-devel (circa 2013-07-17 12:19ish EDT), it was mentioned that journalctl can also use:

  journalctl foo

but that isn't useful for all cases, like python scripts where foo could match python, but not the name of the python program itself.  It was also mentioned that perhaps this mechanism just needs to be made smarter to handle such cases.  That would be equally welcome, if not more so.
