Subject: 24.3.50; cache-long-scans t breaks dired
Date: Wed, 21 Aug 2013 00:59:21 +0200

Hello,

here, cache-long-scans t in dired does speed up moving by lines a lot,
but it also breaks dired.  Every time a file's line is updated, stuff
like

//DIRED// 45 51
//DIRED-OPTIONS// --quoting-style=literal

is inserted into the buffer.  File operations raise errors.

A minimal example from emacs -Q:

- dired a directory
- there, M-: (setq cache-long-scans t)
- on a file, hit l (maybe twice)

Then I get additional lines like above.


Thanks,

Michael.
