[Templates] escaping \n in strings

[Womble]

The pages we're generating have PHP in them on occasion (yes, I know 
this 
is sick and wrong but no one else here knows perl and none of them will go 
to the effort of learning it), and sometimes we need the php to spit out 
'\n', but TT2 keeps eating the \n and printing a new line.  I tried 
escaping the \n with \\n (and \\\n and \\\\n) but that doesn't work.

The trouble I think is that the PHP fragment is a variable in the template 
and, although the $'s and "'s are escaped and behaving, the \n isn't, 
which doesn't make sense.

I assume no one has been sick enough to put PHP in their source files 
before, so this hasn't been noticed?  Or am I just missing something 
obvious?
