find-file-noselect is a huge function which runs major modes, looks for
file-local variables, looks for other buffers already visiting the file,
checks the buffer if it is still uptodate w.r.t the file, ...

It's nowhere near "clean and abstract".
Anybody who expects such a large function to preserve the match-data will
basically expect *every* function to preserve the match-data.
