Currently RunTool reads command's output with asyncio read, which
returns bytes. This is decoded into python's string and the output already
contains OS specific line endings, which on Windows is CRLF. Problem is
that the command output is saved by using python's text stream/file,
which replaces LF, native python's line ending, with OS specific line ending.
On Windows, and in this particular case, the CRLF from the command output is
translated into CRCRLF and saved in the commands output file. When this
file is read in again, e.g. for hint modules, the CRCRLF is replaced
with LFLF. Again the file is open as text file. Meaning a new emply line
is added.
Fix this by opening the output file with "newline=''", which prevents
this translation. We already have the OS specific line ending in the
command's output.
