Fix sleep time option to recognize a numeric argument

[vutny]

Silly bug, possibly introduced by wrong merge.

[s0undt3ch]

Oh, you been bumping the date. That's usually only right before merging to stable, but that's alright...

[s0undt3ch]

Could you take care of this one too since you're at it?

Thanks!

[vutny]

@s0undt3ch I've already fixed it in 1b9ea4f. Jenkins triggered job for wrong PR No 766 again, but the first attempt was correct.

[vutny]

Regarding the version bump, I thought that develop branch went far away from stable currently, and there is no way to determine the exact commit from bug reports...
Especially when people use curl -L https://bootstrap.saltstack.com/develop ....

[s0undt3ch]

The only way to determine is the -dev in the end. If the version of stable and develop match, develop is more recent because of that suffix...

[vutny]

@s0undt3ch Acknowledged, thanks. Will add -dev suffix in further PRs.

[s0undt3ch]

No no. -dev is added automatically :)

[vutny]

@s0undt3ch Strange... I can't find where such thing happen... Maybe you meant this?

 504 echowarn "Running the unstable version of ${__ScriptName}"

This line is commented in stable.

Hmm, yes, that's what I was referring to. Sorry.
