I think Larry was only commenting on not needing to worry about what EOL an
editor will use since CVS will convert ASCII files to use platform specific
EOLs, as long as working files aren't shared across platform, but I thought
I'd clarify for those that may have missed it:

The commitinfo script David described is still fairly safe and possibly a
good idea - if your server is on UNIX, the linefeed conversion will be run
before the commitinfo script gets run, so the commitinfo script can verify
that all lines end in '\n' safely.  The few exceptions might include things
like a test case input file which has one or more lines ending in '\r\n',
but I think a file like that would have caused problems between DOS/UNIX
anyhow and would have had to have been declared binary to CVS to keep it
identical on both platforms.

In other words, David's script should still catch the times someone binary
mode FTP'd the file from DOS and tried to check it in under UNIX.  :)
