Log Message:
-----------
Fix psql history handling:

> 1) Fix the problems with the \s command.
> When the saveHistory is executed by the \s command we must not do the
> conversion \n -> \x01 (per
> http://archives.postgresql.org/pgsql-hackers/2006-03/msg00317.php )
>
> 2) Fix the handling of Ctrl+C
>
> Now when you do
> wsdb=# select 'your long query here '
> wsdb-#
> and press afterwards the CtrlC the line "select 'your long query here
'"
> will be in the history
>
> (partly per
> http://archives.postgresql.org/pgsql-hackers/2006-03/msg00297.php )
>
> 3) Fix the handling of commands with not closed brackets, quotes,
double
> quotes. (now those commands are not splitted in parts...)
>
> 4) Fix the behaviour when SINGLELINE mode is used. (before it was
almost
> broken ;(
