Public bug reported:

Original text:
<VirtualHost *:80>
	ServerAdmin webmaster@localhost
	ServerName ci.company.com
	ServerAlias ci
	ProxyRequests Off
	<Proxy *>
		Order deny,allow
		Allow from all
	</Proxy>
	ProxyPreserveHost on
	ProxyPass / http://localhost:8080/ nocanon
	AllowEncodedSlashes NoDecode
</VirtualHost>

Bash example with \ delineation:
echo -e "<VirtualHost *:80> \n\
	\tServerAdmin webmaster@localhost \n\
	\tServerName ci.company \n\
	\tServerAlias ci \n\
	\tProxyRequests Off \n\
	\t<Proxy *> \n\
		\t\tOrder deny,allow \n\
		\t\tAllow from all \n\
	\t</Proxy> \n\
	\tProxyPreserveHost on \n\
	\tProxyPass / http://localhost:8080/ nocanon \n\
	\tAllowEncodedSlashes NoDecode \n\
</VirtualHost>" >> /etc/apache2/sites-available/jenkins.conf

Output:
<VirtualHost *:80> 
.	ServerAdmin webmaster@localhost 
.	ServerName ci.company.com 
.	ServerAlias ci
.	ProxyRequests Off 
.	<Proxy *> 
.		Order deny,allow 
.		Allow from all 
.	</Proxy> 
.	ProxyPreserveHost on 
.	ProxyPass / http://localhost:8080/ nocanon 
.	AllowEncodedSlashes NoDecode 
</VirtualHost>

However, when combined on one line, like this:
echo -e "<VirtualHost *:80> \n\tServerAdmin webmaster@localhost \n\tServerName ci.company.com \n\tServerAlias ci \n\tProxyRequests Off \n\t<Proxy *> \n\t\tOrder deny,allow \n\t\tAllow from all \n\t</Proxy> \n\tProxyPreserveHost on \n\tProxyPass / http://localhost:8080/ nocanon \n\tAllowEncodedSlashes NoDecode \n</VirtualHost>"

The output looks like this:
<VirtualHost *:80>
	ServerAdmin webmaster@localhost
	ServerName ci.company.com
	ServerAlias ci
	ProxyRequests Off
	<Proxy *>
		Order deny,allow
		Allow from all
	</Proxy>
	ProxyPreserveHost on
	ProxyPass / http://localhost:8080/ nocanon
	AllowEncodedSlashes NoDecode
</VirtualHost>

I believe this to be a bug with the echo() functionality. When used on
one line, there is no period proceeding the horizontal tab delineation.
However, when the echo function crosses multiple lines due to bash
readability with the \ character, it places a period at the beginning of
the line, before the tab delineation.
