Fix clang-format CLion integration bug.
CLion's Sax parser threw this error:
Failed to parse clang-format XML replacements. Input: <?xml version='1.0'?>
<replacements xml:space='preserve' incomplete_format='true' line=89>
[...]
[org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 66; Open quote is expected for attribute "line" associated with an element type "replacements".]
