Allow blank command line arguments

[viseztrance]

Hi,

I was trying to pass an empty argument and noticed that Cocaine would ignore it.

I'm uncertain if this is by design or not, but you should be able to do so. For example the following would not be valid without it (nor without the --data parameter for that matter):

curl -X POST --data '' 'http://localhost:9900'

The following patch addresses this issue (nil arguments are ignored as before).

Thanks, Daniel

That's a very good point. Thanks for the patch. I've pulled it in, and it'll be in the next release.

Understood, thanks!
