doc: convert git-mv to new documentation format

- Switch the synopsis to a synopsis block which will automatically
  format placeholders in italics and keywords in monospace
- Use _<placeholder>_ instead of <placeholder> in the description
- Use `backticks` for keywords and more complex option
descriptions. The new rendering engine will apply synopsis rules to
these spans.

Unfortunately, there's an inconsistency in the synopsis style, where
the ellipsis is used to indicate that the option can be repeated, but
it can also be used in Git's three-dot notation to indicate a range of
commits. The rendering engine will not be able to distinguish
between these two cases.

 SYNOPSIS

-'git mv' [<options>] <source>... <destination>

 DESCRIPTION
 -----------
 Move or rename a file, directory, or symlink.
 
- git mv [-v] [-f] [-n] [-k] <source> <destination>
- git mv [-v] [-f] [-n] [-k] <source> ... <destination-directory>

-a file, symlink or directory, to <destination>.
-In the second form, the last argument has to be an existing
+In the first form, it renames _<source>_, which must exist and be either
+a file, symlink or directory, to _<destination>_.
+In the second form, _<destination-directory>_ has to be an existing
 directory; the given sources will be moved into this directory.
 
 The index is updated after successful completion, but the change must still be
 committed.
 
 OPTIONS
 -------
--f::
---force::
+`-f`::
+`--force`::
 	Force renaming or moving of a file even if the <destination> exists.
--k::
+`-k`::
 	Skip move or rename actions which would lead to an error
 	condition. An error happens when a source is neither existing nor
 	controlled by Git, or when it would overwrite an existing
 	file unless `-f` is given.
--n::
---dry-run::
+`-n`::
+`--dry-run`::
 	Do nothing; only show what would happen
 
--v::
---verbose::
+`-v`::
+`--verbose`::
 	Report the names of files as they are moved.
 
 SUBMODULES
 ----------
 Moving a submodule using a gitfile (which means they were cloned
 with a Git version 1.7.8 or newer) will update the gitfile and
 core.worktree setting to make the submodule work in the new location.
-It also will attempt to update the submodule.<name>.path setting in
-the linkgit:gitmodules[5] file and stage that file (unless -n is used).
