Remove space in help in between -a and [DEVICE]

[pvalena]

As it has otherwise no effect. I made a note in README as well.

Not sure this is correct approach, but also I don't know how to fix this other way in https://github.com/ammen99/wf-recorder/blob/master/src/main.cpp#L693, nor how to report an the unknown arg - this may be a bug.

I didn't edit this in man pages as well, as I'm unsure what's the proper way.

Note that there's a secondary issue- no error is thrown when the device is specified (and ignored), separated by a space (iow as another arg).

Thanks for a great program!

Looks good! However, I suspect the man page will also need similar treatment.

Eh, actually, I think there should be a space for the long option, shouldn't it?

That doesn't work at all:

Sorry I didn't try it.
