Sounds good.

The point for svn:eol-style native is to allow people to check out files 
and edit them on their own box and not have to worry about the end of lines.

If we set the style to LF, then people that do check the files out on 
Windows to edit will have only LFs and not CRLFs in the file and then 
notepad or other simple editors will get a file that appears to be one 
long line instead of a normal looking like file.  So svn:eol-style LF 
prevents people with Windows clients from editing our files easily.

Since we're only running the scripts on Unix OSes, or even Cygwin, then 
when we do a checkout there, the end-of-line is LF, so everything works 
fine.  Now, if we do checkouts on non-Unix OSes where the eol is not LF 
and need to run them and the script process needs LF end of lines, then 
there's an issue, but I don't see this as being a problem since we're 
very unlikely to run into it.  Even in Cygwin, most people have it run 
in LF mode, not CRLF mode.

I think you're trading a known issue that we can run into now (people 
editing these files on Windows systems and wanting to provide the 
correct system end-of-lines to make life easy) vs a problem which isn't 
occurring (running a script with CRLF on a scripting engine that needs LFs).
