The two consecutive colons on the -a line mean the -a option takes
an optional argument.
Herein lies the problem:
```
-a <file> [...] -- attach file(s) to the message
the list of files must be terminated with the "--" sequence
```
So it's neither optional, nor even a single word by necessity.

escape. they're your best educated, your most creative, and your

you a new civilisation." -- porcupine tree, voyage 34
