[ESS] SAS-mode problem with asterisk (infinite loop)

[Jim Berry]

Hi Rodney,

I downloaded and compiled ess-5.2.8.  Same problem with SAS mode.
GNU Emacs 21.3.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2003-08-20

Same problem on Solaris 9 with emacs 20.4 and emacs 21.3.  
I have not tried this on Windows.


emacs -q
M-x load-file ess-site RET
C-x C-f junk.sas  RET
 *;RET   

This stalls until I enter C-g. No problem if the asterisk is in column
1.  We can easily avoid this, but perhaps a subtle indentation bug.

Thanks
Jim
