Show --More-- when reading a scroll of identify

Give people a chance to realize what they've read before throwing the
inventory picker in front of the message area.

This complements commit 4b0225f96c (show --More-- between objects while
identifying).
Give enchant vibrate warning for all weapons/armor

Using a scroll of enchant weapon or armor will now give the
over-enchanting warning message for all weapons and armor, not just
elven gear.
NH4: Make #adjusting to same letter combine all mergable items

NetHack allowed #adjust to combine all inventory items that could be
merged with the selected item.  This was lost in all of the refactoring
done by NitroHack, but was restored by NetHack4, and now it's here.

Support automatic merging in inventory via #adjust

Wrap rewinded messages like printed ones, clear empty lines

The message window becomes really ugly when rewinding during replays.
This commit was part of my attempt to solve this, but the truth is that
deep systemic changes are needed to allow rewinding to fill the message
history and window properly.

Not only does rewinding not prune messages or redraw the message window
like it should, it doesn't even have the data needed to prune the right
messages: replay steps go by fine-grained "action count" (tracked
internally and implicitly by the replay system), but messages are only
annotated with coarse-grained turn count.  Not to mention the message UI
code is a tangle of spaghetti logic and what are essentially global
variables.

So for now, rewinding the message window is now slightly less broken,
but still really ugly.
Fix saved/completed games toggle option in replay listing

The label for the '!' option in the replay choice menu now distinguishes
between saved and completed games, and has been moved to the top of the
menu.  As a bonus, the menu's title also reflects this distinction.
