AFAICS, that's due to b1a765b3a8586cd53c21579982c8fbc0ce534336.

It switched `vc-dir-refresh-files' to call `dir-status-file' without
checking that each implementation doesn't include unwanted files which
might slow down that call.

Although 180K ignored files? Damn, that's a lot.

Should be fixed with 5872f843ff45de150f4b35cbc9b11e9f63c96cf2.
