[R] mysterious extra spaces appearing in expression paste

So I found workaround for what I'm now pretty sure is a bug.
the reason I'm sure it's a bug is that i found that I found that
linebreaks are handled in a wonky but regular way. There's a rule,
and it's a bad rule, ie a bug.
The wonky rule is as follows: text(x,y,expression(paste("thing1
\n","thing2"))) results in printing thing1 at the requested x/y with
the linebreak failing to cause a carriage return. That is, thing2
appears directly below the "1" in thing1.
"\n" in paste doesn't make a carriage return, just a new line.
perhaps there's something like endl that I'm supposed to put in there
and I just don't know. I'll bring this to the attention of
r-bugs at r-project.org .
The workaround for my particular problem was to not use line breaks,
but instead break the legend up into four parts instead of 2, using
the fact that legend puts each legend=c() element on a new line.
leg <- c(expression(paste("data1 \n(",rho,"=1)")),
legend("bottomright",legend=leg,col=c(1,2),lwd=3, y.intersp = 2.0,adj=c(0,1.5))
leg <- c("data1",expression(paste("(",rho,"=1)")), "data2",
note the lty to block the extra lines.
