```
Write the gitk config data to $XDG_CONFIG_HOME/git/gitk ($HOME/.config/git/gitk
by default) in line with the XDG specification. This makes it consistent with
git which also follows the spec.

If $HOME/.gitk already exists use that for backward compatibility, so only new
installations are affected.

Sounds reasonable...

Don't we need to set config_file_tmp here too?

And, do we really want to create the ~/.config/git directory if we are
using the old-style ~/.gitk as the config file?

Yeah it's probably best to keep the two files together.

Probably not. I'll prepare a new patch restoring the old behaviour.
