This is not technically a bug:
$ cat /dev/null | mail -e -s test jeroen
<no mail>
$ echo | mail -e -s test jeroen
<mail>
$
This is because:
$ cat /dev/null | wc
0 0 0
$ echo | wc
1 0 1
$ echo | hd
00000000 0a |.|
00000001
$
(also see echo's -n option)
Note that 'echo' will always output a newline (0x0a). So the body isn't
empty, it contains a single newline / a single empty line.
Of course, this could be special cased, but then, where to stop? Also
special case a single space? And what about other whitespace? Is tab
whitespace? Are the various unicode whitespace characters whitespace?
Note that I'm not the maintainer, so I'm leaving the bug open, but if I
were the maintainer, I'd have closed it now.
