doc: git-log: convert log config to new doc format

- Use `backticks` for keywords and more complex option
descriptions. The new rendering engine will apply synopsis rules to
these spans.
- Explain possible options in description list instead of in a paragraph.

 If the format is set to "auto:foo" and the pager is in use, format
 "foo" will be used for the date format. Otherwise, "default" will
 be used.
 
-log.decorate::

 	Print out the ref names of any commits that are shown by the log
-	command. If 'short' is specified, the ref name prefixes 'refs/heads/',

-	'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is

-log.initialDecorationSet::
+`log.initialDecorationSet`::
 	By default, `git log` only shows decorations for certain known ref
 	namespaces. If 'all' is specified, then show all refs as
 	decorations.
 
-log.excludeDecoration::
+`log.excludeDecoration`::
 	Exclude the specified patterns from the log decorations. This is
 	similar to the `--decorate-refs-exclude` command-line option, but
 	the config option can be overridden by the `--decorate-refs`
 	option.
 
-log.diffMerges::
+`log.diffMerges`::
 	Set diff format to be used when `--diff-merges=on` is
 	specified, see `--diff-merges` in linkgit:git-log[1] for
 	details. Defaults to `separate`.
 
-log.follow::
+`log.follow`::
 	If `true`, `git log` will act as if the `--follow` option was used when
 	a single <path> is given.  This has the same limitations as `--follow`,
 	i.e. it cannot be used to follow multiple files and does not work well
 	on non-linear history.
 
-log.graphColors::
+`log.graphColors`::
 	A list of colors, separated by commas, that can be used to draw
 	history lines in `git log --graph`.
 
-log.showRoot::
+`log.showRoot`::
 	If true, the initial commit will be shown as a big creation event.
 	This is equivalent to a diff against an empty tree.
 	Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
 	normally hide the root commit will now show it. True by default.
 
-log.showSignature::
+`log.showSignature`::
 	If true, makes linkgit:git-log[1], linkgit:git-show[1], and
 	linkgit:git-whatchanged[1] assume `--show-signature`.
 
-log.mailmap::
+`log.mailmap`::
 	If true, makes linkgit:git-log[1], linkgit:git-show[1], and
 	linkgit:git-whatchanged[1] assume `--use-mailmap`, otherwise
 	assume `--no-use-mailmap`. True by default.
