Yes, but notice that the above is about interactive mode "add -i"
that is setting the diff.context to 7 for subsequent "patch"
command, not against "Stage this hunk [y,n,q,...]?" prompt inside
"add -p".  Once you go into the "--patch" mode, especially after you
let the user to edit some hunks, "redisplay this hunk with wider
context" is an impossible operation with the current code structure,
I think, as the implementation does not keep track of information
that are needed to do so.

So, this is like "restarting 'add -p' with -U7", but done from the
"add -i" session.
