code/git/821d56aa68c38f7390b3171092f7b8b814357194 doc: clarify how -S works
The existing text was very vague about what exactly it means
for difference to "contain" a change. This seems to cause
confusion on the mailing list every month or two.
To fix it we:
1. use "introduce or remove an instance of" instead of
"contain"
2. point the user to gitdiffcore(7), which contains a more
complete explanation
