doc/rev-list-options: clarify "commit@{Nth}" for "-g" option

When "log -g" shows "HEAD@{1}", "HEAD@{2}", etc, calling that "commit@{Nth}" is not really accurate. The "HEAD" part is really the refname. By saying "commit", a reader may misunderstand that to mean something related to the specific commit we are showing, not the ref whose reflog we are traversing. While we're here, let's also switch these instances to use literal backticks, as our style guide recommends. As a bonus, that lets us drop some asciidoc quoting.

253 With `--pretty` format other than `oneline` (for obvious reasons),
254 this causes the output to have two extra lines of information
255 -taken from the reflog. By default, 'commit@\{Nth}' notation is
255 +taken from the reflog. By default, `ref@{Nth}` notation is
256 used in the output. When the starting commit is specified as
257 -'commit@\{now}', output also uses 'commit@\{timestamp}' notation
257 +`ref@{now}`, output also uses `ref@{timestamp}` notation
258 instead. Under `--pretty=oneline`, the commit message is
259 prefixed with this information on the same line.
260 This option cannot be combined with `--reverse`.
