bug#6865: 24.0.50; Font lock error in sql mode

From: Tim Cross
Subject: bug#6865: 24.0.50; Font lock error in sql mode
Date: Mon, 16 Aug 2010 10:18:31 +1000

There is an error in the font-lock settings for SQL mode. At a guess,
the problem is that one of the regexp definitions is too aggressive. 

Essentially, any line which starts with the letters rem will result in
that line being font-locked as a comment. This is with using SQL mode to
edit SQL with the Oracle settings. 

Simple recipie to reproduce 

1. Open a buffer in sql mode
2. Ensure you have the product settings set to Oracle
3. Enter the following SQL statement 

UPDATE mytable
SET fld1 = val1,
   remote_user = val2,
   fld3 = val3
WHERE fld4 = val4;

The line remote_user = val2, will be font locked as a comment. 

Note that Oracle supports the REMARK or REM statement for comments. At a
guess, the regexp needs to be updated to only consider lines starting
with REM and a space or REMARK (either upper or lower case) as being a
comment, but not anything else.
