Quoting all excerpts

Hello community ! Is just a little detail, but I found quite useful to give to each excerpt some ” “ signs in order to give them a ‘quote’ look, and I did it just wrapping every <?php the_excerpt)(; ?> in my template with the ” “ signs.

But a little detail is driving me crazy : my excerpts are under a text-align:center css property and the result look like this:

"
Someexcerpt[...]

     "

And I’d like a more standart format like:

“Someexcerpt[…]”

I tried to <span class="beginquote">"</span> and <span class="endquote">"</span> and then .beginquote{float:left}, .endquote{float:right} but the ending quote keeps quite separated from the excerpt, because some extra padding seems to be set by default.

Do you have some suggestions ?

If it is not difficult, I could add the quote signs in the same way as we have by default the […] expression.

Thanks very much if you can help.
