I use TortoiseSVN for version control. In a working cooy I have been working with for weeks, I suddenly see a number of "changed" files showing up in the "SVN commit.." dialog that I have definitely not touched and which do not contain any real differences:

I have not changed these files' encodings not performed any other operation on them as far as I can remember. Does anybody know what this is and how to get rid of it?
EDIT: The behaviour has appeared again. Tortoise is claiming "text change", even though there was none:

this can hardly be a line ending thing, can it? It's not urgent as it happens very rarely now, but I'm still curious.
Edit: All right folks, time to own up. It's really embarrassing but I found out what it was. What I didn't point out, because I thought it wasn't important, was that I was not working in the "commit..." dialog of Tortoise, but in "check for modifications". I think you can gather the rest: I switched back and forth a lot between the IDE and Tortoise, checking in various files, and whenever I would check in a file, not click refresh, do something else and check it in again because I forgot, it wouldn't work - but would of course still be in the list. Thanks for your time! +1'ing every answer and accepting the one who stuck with me the longest :)
All right, let's get out the big guns. :-)
Check out the file (styles.css revision 40) into a separate directory.
Run a program which calculates md5 (e.g. md5, md5sum, or openssl md5) on both your working copy and the repository copy. If you end up with different answers, the files are different and TortoiseMerge isn't showing you something important. If you end up with the same answer (neglecting the infinitesimally probable case where two different but very similar files have two identical md5 hashes), then the files are apparently identical and TSVN has some problem. (maybe it's looking at the file date?)
edit: The only pathological case that crosses my mind is that maybe the file has a different encoding (e.g. UTF-8 vs ASCII)... I upgraded from WinXP SP2 to SP3 several months ago and occasionally I run into weird things (apparently UTF-8 byte order marks) where the first few characters show up strangely in text editors.
Let us know what you find!
