The Apache committers guide suggests setting up your svn configuration to set this property automatically for newly created files, see http://apache.org/dev/#version-control and click on "SVN eol-style. I see our one-time-setup page SVN section is missing this info, so I'll add it.
If you do this setup, the svn property eol-style is automatically set to "native" for new files. Without this, every time someone updates a file on an OS that uses different line ending conventions (Windows vs Linux vs MacOs), the SVN thinks all lines are changed. With this, the files are store in SVN in a standard coding for this, and when checked out, assume the coding of the machine they're checked out on; when checked in, they are converted as necessary to the standard way. -Marshall
