annotate src/imap/cmd-append.c @ 3879:928229f8b3e6 HEAD

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
deinit, unref, destroy, close, free, etc. functions now take a pointer to their data pointer, and set it to NULL. This makes double-frees less likely to cause security holes.
