i guess we did not do that on CVS.

this is part of the svn st -v. looks like no change detected.

u can see the file go back to old size again. so it is recovered to old
file.

now the problem is i migrated last year and never notice this binary
file, i mainly work on source code. then after many commit in svn, it is
hard for me to restart from scratch.
also another information is if i check out from cvs, these files are not
corrupted.
so is there a way to mark one file as modified and commit it even svn
did not detect the change?
my last way will be svn rm it, and svn add back. that is messy...
Thanks!
