[Samba] tiny odd script thing

<p>I have been reviewing Louis' script 
(4-setup-sernet-samba4-MEMBER-wheezy.sh) and within the following line 
(line 310) is an odd character combination at the end of the line:</p>
<p style="padding-left: 30px;"><span style="font-family: book 
antiqua,palatino;">if [ ${SMBPRINTING} = no ]; then</span><br /><span 
style="font-family: book antiqua,palatino;">echo "==========Disable 
Printing ==============================="</span><br /><span 
style="font-family: book antiqua,palatino;">sed -i '49a\\n   # 
disable printing completely\n   load printers = 
no\n   printing = bsd\n   printcap name = 
/dev/null\n   disable spoolss = yes\n'^M</span> <span 
what?</strong></em></span><br /><span style="font-family: book 
antiqua,palatino;"> /etc/samba/smb.conf</span><br /><span 
style="font-family: book antiqua,palatino;">fi</span></p>
<p>I use vi for my editor (Debian 7.7.0) and I noticed that this "^M" 
character was the only colored character in the entire script. This 
character combination (and color) appears twice within the script. Once 
listed above and finally at the last line of the script. This character 
combo seems odd and <em>maybe it is nothing</em>.</p>
<p>Anyone have any thoughts as to what this character is?</p>
<p>(As I know very little about emac editor, is it an "editor" 
<p>And when I 'test' remove the combination, the cursor responds as if 
they are a single character even though it appears as two characters. In 
other words a single keystroke removes both characters.</p>
<p>Should they be removed from the script?</p>
<p>(I feel bad to raise this question while Louis is on a holiday. Many 
of us have been using his scripts for some time now and history 
indicates that they are working scripts. And I for one really appreciate 
all the work that went into them.)</p>
