I'm not the maintainer, just a user - but to me this is correct and 
therefore expected behaviour. The man page indicates that the EVAL 
construct <%= expr %> is shorthand for "echo expr", but it actually 
expands to "echo -n expr".

You can see this by adding --debug flag when calling haserl. This will 
cause it to output all the shell statements, rather than executing them. 
I find this quite helpful when trying to figure out what it is doing.

In the case of using shell=lua, it looks like it expands to:
  io.write(tostring( foo ))
without adding any newline, just like "echo -n". So it seems consistent 
at least.

Best regards,
