+I wonder if it would make sense for this option to be combined with\r
+something like\r
+id:"1341041595-5858-1-git-send-email-markwalters1009@gmail.com" which\r
+chooses whether to output the body of the message or not.\r
+\r
+Maybe something like --output=short|medium|full\r
+with short being just the brief headers, medium being the current\r
+default of brief headers and text bodies, and full being message with\r
+all headers.\r
+\r
+I am not sure I like it (as someone will want full headers and no\r
+bodies!) but we don't want the command line to get too cluttered.\r
+\r
+Another possibility for this particular choice: could a list of wanted\r
+headers be included in the config file? Since I think you want it for\r
+"user wants to see it" reasons rather than "program needs it to do\r
+something" reasons that might make sense.\r
+\r
+Best wishes\r
