While I'd agree this is a good change, the author should justify it in the
commit log message.  I ask list regulars like you to set a good example
for others.

	When a document viewer that is unknown to the current version of
	git is specified in the .git/config file, instead of erroring out
	the process completely, just issue a warning.  It might be that
	the user usually is using a newer git that supports it (and the
	configuration is written for that version) but is temporarily
	using an older git that does not know the viewer.
