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) ] ;
return $(match) ;
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'.
