Hello all Org's developpers,
I would like to provide a small improvement to ob-sql : the possibility to
connect to an oracle database by using the alias defined in TNSNAMES file.
The patch joined here try to achive this. It also improve (slightly) the
data fetching by removing unwanted trailing whitespaces provided by the
LINESIZE directive.

Thank you.
Have you signed FSF papers? Otherwise, you need to add TINYCHANGE at the
end of your message?
Otherwise, it looks good. Would you mind adding an entry in ORG-NEWS
about it?

Normally, I've done this some time ago for TRAMP and EMACS core (I
think).

I'm sorry I did a mistake in the previous patch. There is an
inconsistency between the code in `org-babel-sql-dbstring-oracle' and
the example provided in the ORG-NEWS file.
So I attached two patches:
- the first (0001-ORG-NEWS-...) correct the example in order to match to the code,
- the second (0001-ob-sql.el...) correct the codein order to match to the example.
Personnaly I prefer the last as it match better with the habits of
thoses who uses Oracle's products (We talk almost ever in term of
database than in term of servers).
But it's up to you.

I applied the second patch, with a slight refactoring.
