Weird, when I try, I get without mailto.

$ xdg-email --version
xdg-email 1.1.0 rc3
$ cat ~/bin/emacsmail 
#!/bin/bash

echo "$@">/tmp/xdg-test.log
$ xdg-email foo@bar.fi ;cat /tmp/log
foo@bar.fi


This seems to be because open_gnome3 in that script uses
xdg-mime query default "x-scheme-handler/mailto"
which on my system for some reason gives thunderbird.desktop
instead of what I set it to in Xfce, and open_thunderbird does
MAILTO=$(echo "$2" | sed 's/^mailto://')                                               
I guess that's one for the xdg-email authors.

Aha, that makes sense.

Hmm, now I'm not so sure I should be feature requesting this; even for
hardened Emacs users, it's easy to hit C-c C-c too quickly. I'll
probably continue using your patch myself though …

Not necessarily; xdg-email could turn multiple --attach arguments into a
single delimiter-separated list of file paths. But I'd rather not
suggest a new standard without having done a full survey in case other
programs support multiple mailto:-attachments in various ways :)
