Computing the file URL for pretty printing using
abspath
can fail when the current working directory doesn't exist. This is a quick fix for this issue (which is incredibly confusing/disruptive if the user does manage to enter a nonexistant working directory!)A more complete fix would avoid ever looking at the working directory when printing diagnostics, instead requiring the caller to pass in a richer definition of the "location of source code" than the mere file name as a string. However getting something sensible working there is (a) breaking and (b) unclear on may details. So just patching this up quickly seems good for now.
