From d0fe5ff7e0d8d023945c688f7d31296cfb5ad266 Mon Sep 17 00:00:00 2001
From: Miles Bader <miles@gnu.org>

Subject: (w_deps):   New function. (main):   Initialize dependencies field of
 USER_HOOKS to w_deps. (_w_specs):   Add PS_FMT_FIELD_COLON_MOD to Idle's
 flags. (w_fetch):   Set HAVE bits even if the values are `nominal'.  
 Correctly propagate PS->inapp bits.
