Style/UnneededPercentQ complaining about dynamic string that's using double quote

[DMA57361]

We're using %Q() to wrap a piece of text with double quotes like so %Q("#{text}"), but Style/UnneededPercentQ is telling me this is not acceptable.

The cop states "Use %Q only for strings that ... or for dynamic strings that contain double quotes." so, if I've understood correctly, shouldn't this usage - a dynamic string including double quotes - be acceptable?

Example file:

text = 'something'
result = %Q("#{text}")

Result:

$ rubocop example.rb --only Style/UnneededPercentQ
C

Offenses:

example.rb:2:6: C: Style/UnneededPercentQ: Use %Q only for strings that contain both single quotes and double quotes, or for dynamic strings that contain double quotes.
result = %Q("#{text}")
         ^^^^^^^^^^^^^

I confirmed this as a bug. Also, auto-correct changes that line to result = '"#{text}"'.

Besides the point, but the issue can be worked around with: result = text.inspect

On HEAD, this produces the following warning:

Use % instead of %Q.

...which is correct. Autocorrection also works. Therefore, this issue can be closed.
