bookmarks: rely on exception for malformed lines

Since we already have an exception context open, for other thing, we can
simplify the code a bit and rely on exception handling for invalid lines.

Speed is not the main motivation for this changes. However as I'm in the middle
of benchmarking things we can see a small positive impact.
