If you add a source file to your repository, think about adding those SVN properties:
svn:eol-style = native
svn:mime-type = text/plain
svn:keywords = Date Revision HeadURL Author
The first line checks a file for consistent line endings before it can be commited.
The last line enables the magic tags like $Date: $ (see previous post).
You can also make TortoiseSVN auto-add properties by setting it up in the [auto-props] section of your SVN config file (%APPDATA%/Subversion/config). Here are some useful lines:
[auto-props]
*.cpp = svn:mime-type=text/plain;svn:eol-style=native
*.hpp = svn:mime-type=text/plain;svn:eol-style=native
*.h = svn:mime-type=text/plain;svn:eol-style=native
*.c = svn:mime-type=text/plain;svn:eol-style=native
*.dbc = svn:mime-type=text/plain;svn:eol-style=CRLF
*.doc = svn:needs-lock=true;svn:mime-type=application/msword
