I'd really, really suggest sticking with the spell as written, which makes no mention of affecting every item the character owns when you target him with a dispel.
Note that there's a big difference between suppressing a permanent magic item, which requires a targetted dispel
on the item, and dispelling a spell effect cast on a piece of a character's equipment.
Say we have a cleric with Bless and Bull's Strength, and GMW on his +1 Mace of Disruption, and MV on his shield and armor.
If equipment counts as part of the character:
An area dispel takes out one of the 5 spells.
A targetted dispel on the cleric could take out all 5 spells.
A targetted dispel on the mace could knock off the GMW,
and suppress the +1 and Disruption qualities.
If equipment is separate:
An area dispel takes out either Bull's Strength or Bless, and gets all three other spells.
A targetted dispel on the cleric gets Bull's Strength and Bless, but not the others.
A targetted dispel on the mace could knock off the GMW,
and suppress the +1 and Disruption qualities.
The Sage's reply states that the first case holds, which makes targetted dispels more powerful. If you take the other view, area dispels become more nasty.
