  2. Next, append a `[local]` section pointing to the wrapper defined
     above:
 
         $ cat >>${XDG_CONFIG_HOME:-~/.config}/interimap/config <<-EOF
+
 			[local]
 			type = tunnel
 			command = exec ~/.local/bin/dovecot-imap
-
 		EOF
 
+    (The command will be passed to `` `/bin/sh -c` `` as it contains
+    the metacharacter `~`.  We use the `exec` built-in utility so the
+    shell process doesn't linger around during the IMAP session.)

  3. And finally append a `[remote]` section with your account
     information at `imap.example.org` (adapt the values accordingly):
 
         $ cat >>${XDG_CONFIG_HOME:-~/.config}/interimap/config <<-EOF
+
 			[remote]
 			type = imaps
 			host = imap.example.net
