source: functions.c @ ab9bf01

release-1.8release-1.9
Last change on this file since ab9bf01 was 3f82515, checked in by David Benjamin <davidben@mit.edu>, 10 years ago
Rewrite aimwrite This now makes more gratuitous use of glib and should, as a bonus, be more sensible. In particular, we now consistently handle multi-word recipients with and without -m. Also avoid duplicating sending code.
