What about different text files?

I mean that text files may use different line endings on different 
platforms: LF, CRLF, CR, other?

At now bzr save in the repository actual line endings from edited file.
I often faced with problem, when after patching some of bzrlib/* python 
files on Windows all line endings was changed to CRLF by patch utility 
and following diff show me that all file content is deleted and then 
added with patch changes. So I need convert patched files to LF line 
endigns manually. It's not difficult, but sometimes I forget about this.

I think it will be useful if inventory will save for each text file 
additional metadata about used line endings:

* Actual (the same as in file on disk, used in current bzr implementation)
* LF
* CRLF
* CR
* other?

In this case when edited file pass through diff command then difference 
in line endings can be ignored if metadata say that file stored with LF 
line endings. When commit this file it will be stored in repository with 
LF only lineendings regardless of actual state on disk (and may be 
change file on disk for sync purposes).

May be this idea is too stupid, but I every day face with different line 
endings during multiplatform development.
