[OS X TeX] line breaks \n vs. \r ???

[Steffen Wolfrum]

Hi,

when editing in TextWrangler a line break is found when using Grep  
and search for \r.
In TeXShop  a line break is found when using Regular Expressions and  
searching for \n: \r gives no result!

Now, I thought there are "More Options" ... "Serach syntax" can be  
changed.
But when I change here also to "Grep" then \r doesn't find line- 
breaks but the letter r !!

Is this a bug in TeXShop 2.14 ?
