git add -p: new "quit" command at the prompt.

moy · gitster · commit 9a7a1e03d5e5 · 2009-04-15T19:41:35.000-07:00
There's already 'd' to stop staging hunks in a file, but no explicit
command to stop the interactive staging (for the current files and the
remaining ones).  Of course you can do 'd' and then ^C, but it would be
more intuitive to allow 'quit' action.
