SAS mode peculiarity

[Na Li]

While editing SAS code:

data a;
    infile 'a.txt';
    input a;
    ^run;

where ^ indicates cursor position.  If I run `ess-sas-backward-delete-tab
(trigged by ';', for example) it becomes:

data a;
    infile 'a.txt';
    inputrun

The reason is because I have

(setq backward-delete-char-untabify-method 'all)

in my .emacs.

One way of dealing with the program is to reset
backward-delete-char-untabify-method locally in
ess-sas-backward-delete-tab.  A patch (against 5.2beta4) is attached.

Cheers,

Michael
