" Unfortunately git-diff does not do CRLF conversion for input received on
" stdin, and git-show never performs CRLF conversion, so repos with CRLF
" conversion report that every line is modified due to mismatching EOLs.

" Instead, we write the buffer contents to a temporary file - myfileB in this
" example. Note the file extension must be preserved for the CRLF
" conversion to work.

" Regarding line endings:
"
" git-show does not convert line endings.
" git-diff FILE FILE does convert line endings for the given files (but not
" for a file piped on stdin).
"
" If a file has CRLF line endings and git's core.autocrlf is true,
" the file in git's object store will have LF line endings. Writing
" it out via git-show will produce a file with LF line endings.
"
" If this last file is one of the files passed to git-diff, git-diff will
" convert its line endings to CRLF before diffing -- which is what we want --
" but also by default output a warning on stderr.
"
" warning: LF will be replace by CRLF in <temp file>.
" The file will have its original line endings in your working directory.
"
" When running the diff asynchronously, the warning message triggers the stderr
" callbacks which assume the overall command has failed and reset all the
" signs. As this is not what we want, and we can safely ignore the warning,
" we turn it off by passing the '-c "core.safecrlf=false"' argument to
" git-diff.
"
" When writing the temporary files we preserve the original file's extension
" so that repos using .gitattributes to control EOL conversion continue to
" convert correctly.
