+Hi Jesse,\r
+\r
+thanks for this. I wanted to do this since the --format=raw was merged,\r

+\r
+I added a comment to the script to explain the sleep there. Otherwise,\r
+people may delete the command because they think it is not needed.\r
+\r
+\r

+\r
+I think that quoting with\r

+instead of sed would work more reliably (see bash(1)).\r

+\r
+In another project I worked around the dead sockets this way:\r
+\r
+sshgw() {\r
+ local socket="$HOME/.ssh/cangw-connection"\r
+\r
+ if [[ ! -S $socket ]] || ! ssh -x -a -S $socket root@192.168.2.3 true; then\r
+ # Create master connection to speed up subsequent commands.\r
+ ssh -N -f -M -S $socket root@192.168.2.3 >/dev/null 2>&1\r
+ fi\r
+ ssh -x -a -S $socket root@192.168.2.3 "$@"\r
+}\r
+\r
+I guess this should work even for notmuch.\r
