This commit makes the releasenotes to use 'inline literal markup[0]
because it would be accurate rendering for commandline
options. Otherwise, dashes are changed into an en/em dash entity. And
this commit also fixes some inline literal markups which I
noticed. Ideally, we should fix like that things in one
patch. However, it's a bit hard to find them all..

This commit tidies up releasenotes. Originally, release note files are
in one directory. So, when I see the directory, I feel ""what a mess!".
So this commit tries to improve it.
