Graphics, Figures & Tables ⇒ Get equal above/belowskip regardless of float for lstlisting

[pauljlucas]

When using the listings package, for some listings I do not want to use float, i.e., I want the listing "inline." The minimal example below shows such a listing. The first lstlisting does not use float and the spacing above/below it is correct, i.e., a blank line.

For longer listings, however, I do want to use float. The second lstlisting does use float, but the spacing above/below it is incorrect — specifically, it's too big as if it were two blank lines.

(The length of the second listing is short since that's all that's necessary to illustrate the problem.)

I want the spacing above/below listings with float to be the same as those without. How can I get what I want?
