Sounds good.

Seeing in diff.c

    static int diff_context_default = 3;
    static int diff_interhunk_context_default;

that they are of signed type, and negative context would not make
sense (would it???), wouldn't -1 be a good "they haven't touched
this from the command line or configuration" value?
