[Boost-build] SHELL and trailing newlines

Hi,
at the moment it's not easy to use SHELL with pkg-config, like this:

   LIBXML_INCLUDES = [ SHELL "pkg-config --cflags libxml-2.0" ] ;

because pkg-config outputs a trailing newline, and then
  
    <cflags>$(LIBXML_INCLUDES)

apparently does not work. Unix shell, when it process command substitution, 
e.g.

       `pkg-config --cflags libxml-2.0`

removes trailing newline. I wonder if we should do the same in SHELL?
