Puppet users - Nov 2013 - Looking to repair "Unrecognised escape sequence" if possible

The recent traffic about " puppet master --compile ... " got me
tinkering with it.

I found a lot of old syntax in my templates, so I added "@" in front
of all the current scope variables.
That got rid of all the grumbles but one: 

Warning: Unrecognised escape sequence ''\1'' 
Warning: Unrecognised escape sequence ''\2'' 

from one of my manifests/init.pp files. 

The offending code can be found here: 

https://github.com/mcgonagle/puppet_nist/blob/master/nist/modules/umask/manifests/init.pp

...at the end of the file, 

define umask-replace($file) { 
exec { 
"umask_replace_${file}": 
command => "/bin/sed -i -r ''s/(umask)([
\t]*)[0-9]{3}/\1\2077/gi'' $file",
onlyif => "/usr/bin/test `/bin/egrep -i
''(umask|UMASK)[[:space:]]*[0-9]{3}'' $file | /bin/egrep -v -i
''(umask|UMASK)[[:space:]]*077'' | /bin/wc -l` -ne 0";
} 
} 

Specifically, the "command" line 

Besides the fact that Unrecognized is misspelled (I copied/pasted out of the
command output) ,
can anyone suggest a fix to remove the warnings ?

Since you''re in a double quoted string, I assume the \1 and \2
backreferences need to be escaped:

  "/bin/sed -i -r ''s/(umask)([
\t]*)[0-9]{3}/\\1\\2077/gi'' $file",
