source: functions.c @ b2bfe1f

Last change on this file since b2bfe1f was b2bfe1f, checked in by Jason Gross <jgross@mit.edu>, 10 years ago
Fixed a bug in the expunge command Expunging from past the end of the message list (e.g., the key strokes d > > x) no longer brings you to the first message. Additionally, the code in owl_function_expunge that is relevant to redisplaying after messages are removed from the message list was placed in helper functions, in preparation for the next commit.
