[clang-format] Make sure rst documentation matches comments

[wanders]

Summary

clang/docs/tools/dump_format_style.py is used to read the comments
from clang/include/clang/Format/Format.h and update the contents of
clang/docs/ClangFormatStyleOptions.rst

Recent changes made these out of date. This commit syncs them by
folding the improved wording back to the comments and then
regenerating the rst file.

Thanks for doing this..

clang/docs/ClangFormatStyleOptions.rst

**UseTab** (``UseTabStyle``)
   * ``UT_AlignWithSpaces`` (in configuration: ``AlignWithSpaces``)
     Use tabs for line continuation and indentation, and spaces for
     alignment.
 
   * ``UT_Always`` (in configuration: ``Always``)
     Use tabs whenever we need to fill whitespace that spans at least from
     one tab stop to the next one.

 **WhitespaceSensitiveMacros** (``std::vector<std::string>``)
-  A vector of macros which are whitespace-sensitive and should not be touched.
+  A vector of macros which are whitespace-sensitive and should not
+  be touched.
 
   These are expected to be macros of the form:
 
   .. code-block:: c++
 
     STRINGIZE(...)
 
   In the .clang-format configuration file, this can be configured like:
 
   .. code-block:: yaml
 
     WhitespaceSensitiveMacros: ['STRINGIZE', 'PP_STRINGIZE']
 
-  For example: BOOST_PP_STRINGIZE.

+  For example: BOOST_PP_STRINGIZE

 Adding additional style options
 ===============================
 
 Each additional style option adds costs to the clang-format project. Some of
 these costs affect the clang-format development itself, as we need to make
