Building scm with the feature "edit-line", or compiling "edline.c" to
a dll (and doing (require 'edit-line)) will enable history and line
editing via the GNU Readline package.

See http://swiss.csail.mit.edu/~jaffer/scm_5.html#SEC84

http://tiswww.case.edu/php/chet/readline/readline.html describes the
readline package.  You can configure readline to complete a set of
names like "define" in the .inputrc file in your home directory, or by
calling functions in the readline C library.  By calling functions in
the readline C library, one could also implement completion of
variable names.  But "edline.c" as it exists currently is minimal.  If
someone figures out from
http://tiswww.case.edu/php/chet/readline/readline.html what needs to
be called in the readline library, then I will add hooks and wrappers
for those functions to "edline.c", and SCM will have the spiffy
completion behavior you are interested in.
