Summary:
While Xcode combines the contents of multiple lines beginning with /// into a single block of documentation, it does not insert whitespace into them, at least in Objective-C.  (In a Playground, whitespace is inserted between the lines.)

Steps to Reproduce:
1. Create a new project (command line tool is simplest).
2. Declare a function and put two triple-slash comments above it (e.g., “///first” and “///second”).
3. Option-click on the function name to display the in-line documentation.
4. Observe that the two lines are concatenated without any space between them (e.g., “firstsecond”).

Expected Results:
Whitespace (specifically, at least one space character) is inserted between the concatenated lines (e.g., “first second”).

Actual Results:
The lines are concatenated without any space between (e.g., “firstsecond”).

Regression:
Occurs in OS X command line tool project with Objective-C file.  Does not occur in Playground.
