  Author: dan
    Path: /home/cvs-pacman/pacman-lib

Modified: lib/libalpm/conflict.c (1.43 -> 1.44)
          lib/libalpm/deps.c (1.74 -> 1.75) lib/libalpm/deps.h (1.18 -> 1.19)
          lib/libalpm/package.c (1.82 -> 1.83)
          lib/libalpm/trans.c (1.40 -> 1.41)
          src/pacman/trans.c (1.40 -> 1.41)

* A little more hacking with wchar_t output, but nothing really changed in
  it. Eventually we'll make progress.
* Rewrote the _alpm_splitdep function to behave more like all our other
  function calls. Use heap instead of stack allocation for the depend struct,
  so now it needs to be freed by the caller.
