Use \n.

hmm... my original post had the "\" in there; not sure why it's missing in your quote.

In any case, I did try \n but it didn't seem to work. Here's a rule I wrote (based on the aforementioned strip-eol from mpi.jam):

rule rtrim ( string )
{
local match = [ MATCH "^(.*)[\n]$" : $(string) ] ;
if $(match)
{
return $(match[1]) ;
}
else
{
return $(string) ;
}
}

Note that I've tried it with and without the [] .

I looked at regexp.c and I can't see where it handles \n -- I'm not sure it actually does. Unless I missed something, I think it treats '\n' as just 'n'.
