bugfix

Hi,

I found a subtle bug in SGML.c. Not sure why I didn't see it before.

In a sequence '<TD>something\n\t\</TD>' I got a first call to SGML_write
terminating at the newline.
This leaves the SGML state set to S_nl.

On the next SGML_write I see the processing of the tab character going through
the S_nl switch case,
incrementing the count variable and then jumping to S_text. In there the
character is not a special
case and so it will cause the count variable to be incremented again.

Next character, the '<' goes into S_text again, and at this point output the
saved characters,
before changing the state into S_tag. The only character that should be passed
through is the
tab, but the count is now 2 and the following '<' is sent to the HTML parser
(and printed out,
in my application).

It looks to me that the S_nl switch case shouldn't increment count, but go
straight to S_text,
so that the counter is 1 and only the tab character is then sent out.

Am I missing something ? I tried the following patch and it seems to work, in
my specific
case. I'll do some more testing and if they are fine and nobody else complains
:) I will
check this change in.

Thanks,

    Raffaele
