As far as I can see this already works fine when reading from and
writing to the repository. However, it will miserably fail when applying
patches to the local files.

If I create a patch on Windows, which is them applied and committed on
Linux and later checked out on Windows again, then weird line endings
(in the patched regions only) may result. I have no solution to this
other than making sure that all patches should contain Linux line
endings and need to be converted before applying the patch under Windows.

Some time ago I wrote a small Windows tool which is able to handle all
kind of line ending problems, even when mixed in a single file. In
certain situations you may need more than one pass. I made it available
for download at

Feel free to use and distribute it in any way. Without any guarantee, of
course. If called without argument, it will display a short help message:

Usage: eolmod [options] <source file> [<target file>]
Options:
  -a Append LF character after each CR character (mac2dos)
  -A Prepend CR character before each LF character (unix2dos)
  -k Kill all CR characters (dos2unix)
  -K Kill all LF characters (dos2mac)
  -r Replace each CR characters by LF character (mac2unix)
  -R Replace each LF characters by CR character (unix2mac)
  -u 'Undouble' CR characters
  -U 'Undouble' LF characters
  -v Increase verbosity
