	# The Desktop Entry Specification does not allow field codes like %u
	# inside a quoted argument, therefore we need a shell wrapper.

	#   u=${1//\\/\\\\}
	#   u=${u//\"/\\\"}
	#   exec emacsclient --eval "(message-mailto \"$u\")"
	# However, in the desktop entry '"', '\', and '$' must be escaped
	# as '\\"', '\\\\', and '\\$', respectively. Yet another level of
	# backslash escapes is needed for '\' and '$' in the here-document.
