Tiny patch on print.c of psql

Hi all,

This is my 1st patch ever in C :-)... I was just borried by a bad psql
\H html output of an EXPLAIN

because it didnt respected spaces sent from backend like:

-> Sort
    -> Sort

I just remarked in this print.c the case of a white space wasnt handled
in the function escaping special caracters to HTML codes, so I added it
replacing a space by special html " " (& n b s p).

So we'll have now:

-> Sort
  -> Sort

... in the html generated

(see example at http://www.pack-solutions.net/~jpargudo/explain.html)

Then, every single space in the html source is replaced by this. The
source looks ugly, yes, I will look to *only replacing starting spaces*
of each row of the EXPLAIN, thats will be my 1st patch ever, version 2 :)

So I post this patch only FYI..  I had much fun playing with C a bit :-)
(yes, I dont code C, just a bit of Perl and Python).

Cheers! Thanks again for such a powerfull release.
