Sure, something like this (not yet tested):
-Exec=bash -c "u=\\${1//\\\\\\\\/\\\\\\\\\\\\\\\\}; u=\\${u//\\\\\\"/\\\\\\\\\\\\\\"}; exec emacsclient --alternate-editor= --display=\\"\\$DISPLAY\\" --eval \\"(message-mailto \\\\\\"\\$u\\\\\\")\\"" bash %u
+Exec=sh -c "u=\\$\\(echo \\"\\$1\\" | sed \\'s/[\\\\\\"]/\\\\\\\\\\&/g\\'\\); exec emacsclient --alternate-editor= --display=\\"\\$DISPLAY\\" --eval \\"(message-mailto \\\\\\"\\$u\\\\\\")\\"" sh %u
Sorry, but it doesn't get less ugly. :) Also, it will now call _two_
external programs. Is this acceptable, and is it guaranteed that sed
will be available on users' systems?
