"If". Continuing that line of thought, wouldn't it be possible that the 
ID file contains only files from outside of its subtree in its index? 
Then the prompt will be entirely wrong.

When I say (or read) "search in directory", I understand it to mean the 
subdirectories, too.

But why would that be an error? "Nothing found" is an entirely 
legitimate result.

Since we've encountered a bug in the code, maybe some extra assertions 
in `semantic-symref-parse-tool-output-one-line' (or in its caller?) 
would take care of that.
