Disclaimer: I'm still rather new to Chicken, etc, but it seems to me that things 
would be clearer using a regex-literal:

#;6> (use regex-literals)
; loading /usr/local/lib/chicken/3/regex-literals.so ...
#;7> (string-match #/^\\(.*)\s*$/ "\\foo ")
("\\foo " "foo ")

Of course the .* match is greedy, so it matches any spaces after "foo" as well, 
which may or may not be your (Matthew's) intention.  If not, this might work:

#;8> (string-match #/^\\(.*?)\s*$/ "\\foo ")
("\\foo " "foo")
