Subject: [PATCH v3 05/21] Documentation/applying-patches.txt: convert it to ReST markup
- use the correct markup to identify each section;
- Add some blank lines for Sphinx to properly interpret
the markups;
- Remove a blank space on some paragraphs;
- Fix the verbatim and bold markups;
- Cleanup the remaining errors to make Sphinx happy.
