Details:

See attachments for example scripts.

=== Script "bug-modifier-weechat-print-1.scm" ===

  This script demonstrates a weechat error when trying to invoke the desired
callback with individual parameters.


=== Script "bug-modifier-weechat-print-2.scm" ===

  This script demonstrates a crash when trying to invoke weechat:print after
setting the modifier callback.


=== Script "bug-modifier-weechat-print-3.scm" ===

  This script demonstrates a proper implementation of the weechat_print
modifier callback using a single parameter that receives a list of arguments.


Suggested fix:  add note to documentation to indicate that, unlike python or
c, guile callbacks use a single parameter to receive a list of four
arguments.
