diff: diff.context configuration gives default to -U

Browse Source 
Introduce a configuration variable diff.context that tells
Porcelain commands to use a non-default number of context
lines instead of 3 (the default).  With this variable, users
do not have to keep repeating "git log -U8" from the command
line; instead, it becomes sufficient to say "git config
diff.context 8" just once.
