Changes since version 0.3

* User level changes

** Configurable use of overlay arrow

Use of the overlay arrow to indicate the source location where the
debugger has stopped is now configurable: see
`giguile-use-overlay-arrow'.

* Bug fixes

** Incorrect use of global comint hooks

giguile.el now adds its filter functions to the buffer-local value of
the comint-output-filter-functions hook, not the global value.

** Highlighting backquoted expressions

Source location highlighting for backquoted expressions didn't work;
now it does.

** Proper tail recursion

The command loop implementation (ossau command-loop) was not properly
tail recursive; now it is.
