`parse.file_contents` doesn't find nested imports

The parse.file_contents function (mentioned here) doesn't seem to support imports that are indented (such as in a try block or in a function). This is in contrast to identify.imports, which does seem to find these imports. The issue with using the latter is that it doesn't include comments in the return value, and I'm interested in getting import comments.

Is there an intended difference between these two functions? Is one deprecated? It looks like it might be as simple as adding .strip here or in general modifying those few lines to match how identify.imports does it. Alternatively, maybe identify.imports could be modified to return comment data?

Thanks!

Compare isort/parse.py around line 256 with isort/identify.py around lines 81-84 and line 95, then reproduce how parse.file_contents handles indented imports and comments. Clarify whether parse.file_contents or identify.imports is the intended entry point; done means nested imports are found without losing the import comments the issue requires.
