Use double backticks instead of single, as single backticks produces
italic formatting.

 libcxx supports being built with clang-cl, but not with MSVC's cl.exe, as
-cl doesn't support the `#include_next` extension. Furthermore, VS 2017 or
+cl doesn't support the ``#include_next`` extension. Furthermore, VS 2017 or
 newer (19.14) is required.
 
 libcxx also supports being built with clang targeting MinGW environments.

 If Git for Windows is available, that can be used to provide the bash

 Alternatively, one can also choose to run the whole build in a MSYS2
 shell. That can be set up e.g. by starting a Visual Studio Tools Command
 Prompt (for getting the environment variables pointing to the headers and
 import libraries), and making sure that clang-cl is available in the
 path. From there, launch an MSYS2 shell via e.g.

 Also note that if not building in Release mode, a failed assert in the tests
 pops up a blocking dialog box, making it hard to run a larger number of tests.
