Bug 1278768

This bug is also present on RHEL7

Version-Release number of selected component (if applicable):
file-5.11-31.el7.x86_64

+++ This bug was initially created as a clone of Bug #1243650 +++

Description of problem:
For some servers, when we execute the file command against /var/log/messages , we get the below results :-

[root@server ~]# file /var/log/messages
/var/log/messages: ASCII Pascal program text


Version-Release number of selected component (if applicable):

On RHEL6
file-5.04-21.el6.x86_64

On RHEL7
file-5.11-21.el7.x86_64

On 

How reproducible:
Always/Consistently

Steps to Reproduce:
Actually, the issue is observed if we have PASCAL related words in /var/log/messages however, I have demonstrated below for a general testfile and the test results hold good for /var/log/messages in RHEL6 and RHEL7. RHEL5 does not seem to be affected.

[root@RHEL6-server ~]# echo hello from localhost > testfile
[root@RHEL6-server ~]# cat testfile 
hello from localhost
[root@RHEL6-server ~]# file testfile
testfile: ASCII text
[root@RHEL6-server ~]# echo record >> testfile
[root@RHEL6-server ~]# cat testfile 
hello from localhost
record
[root@RHEL6-server ~]# file testfile
testfile: ASCII Pascal program text  ==> Issue reproduced

[root@RHEL7-server ~]# echo hello from localhost > testfile
[root@RHEL7-server ~]# cat testfile
hello from localhost
[root@RHEL7-server ~]# file testfile
testfile: ASCII text
[root@RHEL7-server ~]# echo record >> testfile
[root@RHEL7-server ~]# cat testfile 
hello from localhost
record
[root@RHEL7-server ~]# file testfile 
testfile: Pascal source, ASCII text  ==> Issue reproduced


Actual results:
After the record word insertion (which is a PASCAL related word) , we see this :-
[root@RHEL6-server ~]# echo record >> testfile
[root@RHEL6-server ~]# cat testfile 
hello from localhost
record
[root@RHEL6-server ~]# file testfile
testfile: ASCII Pascal program text

[root@RHEL7-server ~]# echo record >> testfile
[root@RHEL7-server ~]# cat testfile 
hello from localhost
record
[root@RHEL7-server ~]# file testfile 
testfile: Pascal source, ASCII text


Expected results:

[root@RHEL6-server ~]# echo record >> testfile
[root@RHEL6-server ~]# cat testfile 
hello from localhost
record
[root@RHEL6-server ~]# file testfile
testfile: ASCII text

[root@RHEL7-server ~]# echo record >> testfile
[root@RHEL7-server ~]# cat testfile 
hello from localhost
record
[root@RHEL7-server ~]# file testfile 
testfile: ASCII text


--- Additional comment from Jan Kaluža on 2015-07-16 05:38:14 EDT ---

This is caused by File magic entry for Pascal:

0	regex		\^program	Pascal source text
!:mime	text/x-pascal
0	regex           	\^record		Pascal source text
!:mime	text/x-pascal

If line is file is starting with "program" and "record", the file is identified as Pascal source.

Upstream has removed these weak patterns recently, we could do the same in RHEL6.
