This is pretty old by now and I already saw replies by others (that's
how Myrealbox worked the last few weeks, hope this gmail will do
better), but yet I am surprised that unix commands would touch
hidden directories - that's what .svn folders are, aren't they? -
except when told so explicitly. I wonder what result svn update
would have had, now that those files were modified and recognized
as such by SVN again - would it have taken those former non-
committed changes as fresh modifications or overwritten with the
original stuff still in the repository? Having seen some data loss
recently related to mtime this way or another I guess the latter.
We probably can be glad that the find&replace tools we use here
(Homesite, SciTE, a perl script) don't touch the .svn pristine
copies. (BTW as someone run into this by use of a hex editor just
having done a patch in an Apache DLL the clean way, not in SciTE
as I had come to be used to, I can confirm that HxD does not
change mtime either, and I have not found any option for [un]setting
this behaviour. Luckily this file is not under SVN protection!)
