        * gappinfo.c:
	Add doc comment about uris vs GFiles to
	g_app_info_launch()
	
        * gdesktopappinfo.c:
	Ensure uris passed to g_app_info_launch_uris()
	are not roundtriped through GFile (as that
	may be slightly destructive for e.g. mailto: links)

* can fail to start if it runs into problems during startup. There is
* no way to detect this.
*
* Some URIs can be changed when passed through a GFile (for instance
* unsupported uris with strange formats like mailto:), so if you have
* a textual uri you want to pass in as argument, consider using
* g_app_info_launch_uris() instead.
*
* Returns: %TRUE on successful launch, %FALSE otherwise.
