Please read the thread [1] that I linked in my previous response 
carefully.
I know, there's _a lot_ of text, but I already tried to sum it all up in 
my
previous response.  There's even a video clip [2] in that thread that 
shows
the issue with the corrupted scrollback in a terminal emulator.

Frankly, the "-c pager.add=false" approach is a bit cumbersome.  
Basically,
the new "-P" option would be like "-c pager.add=true", while the already
existing "-p" option would be like "-c pager.add=false".  Though, I 
think
that we don't want to add "pager.add" as a new configuration option, 
because
throwing it into the mix would make the "-p" and "-P" options for "git 
add"
quite confusing.

As another idea, we might also add "p" as another option in the 
"y/n/q/a/d..."
menu when the user decides about each hunk in "git add -p" or "git add 
-P".
When running "git add -p", pressing "p" would display the current hunk 
using
the pager (which would be opposite to the "git add -p"'s behavior of not
using the pager), and when running "git add -P", pressing "p" would 
display
the current hunk by bypassing the pager (again, opposite to the "add 
-P"'s
behavior).  That would allow greatest level of flexibility.
