When using a non-bundled Pygments (which is required on Windows, as the
bundled version is an ELF binary), we call into the Pygments executable
to generate the list of supported languages (lexers). This list seems to
occasionally include carraige returns, causing some languages to not be
processed correctly. Trim those CRs out so the language list is
accurate.
