tabs ignored in here document

[Robert Moskowitz <rgm@xxxxxxxxxxxxxxx>]

I thought this worked.  Many web pages tell you it works.  But bash is 
ignoring tabs in my here docs.  Worst, where there are two tabs, it is 
functioning as a command expand in bash, where all files in the current 
directory are listed to complete the command.

The following is the here doc I am using.  Most likely the tabs will be 
converted to spaces in this email.  But the bottom line is, that while 
processing all the double tables, all the files in the current directory 
get listed, and the resultant file is all flush left, as if I had used 
the +EOF option:

Thing is, I thought I tested this previously, so it is possible that 
there is now something wrong in my environment causing the problem?

cat <<EOF>00-init.conf || exit 1
ServerAdmin $admin_email
ServerName $your_host_tld
<VirtualHost *:80>
    <Directory "/var/www/html">
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>
<VirtualHost *:443>
    SSLEngine On
    SSLCertificateFile /etc/pki/tls/certs/$your_host_tld.crt
    SSLCertificateKeyFile /etc/pki/tls/private/$your_host_tld.key
    <Directory "/var/www/html">
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>
EOF

thanks
