There are two problems:

- you expect the doc to mention the functions that wipe-out the
  match-data (whereas what really happens is that only a few functions
  can be assumed to preserve that data and all others should be assumed
  to wipe it).  Hopefully this thread will fix this ;-)
- Emacs does not document which functions can be trusted not to wipe the
  match-data :-(
