fix(bin/linja): replace windows newline '\r\n' to unix newline '\n'
...
This should be handled by Python. However, when we use mingw-python
which acts like Unix Python with Native Windows Emacs, we have a problem
because mingw-python do not handle '\r'. This patch manually replace
'\r\n' with '\n' to solve the problem.
