 In working on a plugin recently, I came across a couple of lines in core
 that effectively append a specified path to a URL in several functions,
 namely `home_url()`, `content_url()`, `plugins_url()` and so on.

 By my count, these same two lines are used in at least 10 functions, so I
 propose we wrap them into a new `append_path` function, though the name
 could be reworked.

 As a side note, I'm not a huge fan of assigning `$url` twice but don't
 feel like this falls under the pervue of `set_url_scheme()` at all. Open
 to suggestions, though.

 Patch attached.
