Missing space in error message

[middlingphys]

There is some missing spaces in the error message about --query.

In bash or similar "NIX" based shells used in "NIX" environment, escaping can be done byusing double quotes inside single quotes.

If using PowerShell in Windows environment, escaping can be done by using double quoteswith double escape character `.
