Well, I'm an Old Fogie. Twenty plus years of looking at '<' and '>', and not having the context unless I ask for it... I suppose there might be some other old fogies out there, if we haven't all died off.

Right, and us Old Fogies appreciate you Young 'Uns doing that for us. My point is that these options should be provided for in the config file, *as well as* on the command line. (We don't like typing it every time. Arthritis, I 'spect.)

Well, it wouldn't be inevitable if the dadburned config file treated 'diff-cmd' the same way it already treats 'editor-cmd', namely that you can supply parameters right there. (There are a host of other parameters to e.g. the gnu 'diff' that one might also want to pass on.)

Not half as sorry as you'll be when you get to my age.
