[Boost-build] Unexpected line feed when capturing shell output

Hi guys,

I am trying to capture output of a shell command in local variable to be used in a <define> later on. However I am running into some trouble, specifically that a line feed is also captured:

local MY_LOCAL = [ SHELL "echo test" ] ;
echo "before$(MY_LOCAL)after" ;

It yields this output:

beforetest
after

Where I was hoping for:

beforetestafter

Is it expected that a line feed is captured in the local variable? Have tried with piping into "head -1" etc.

Any helpful pointers appreciated.

Best regards,
