Regarding Wish and Limited Wish, I also tend to strongly weigh the results against the player's intent, the source of the wish power, and the wording chosen.
Especially when drafting power for a wish from nefarious sources (demons, efreeti, etc) the wish you want and the wish you get are often something far apart. For example, when presented with an "Efreeti Bottle" and summoning forth the imprisoned Efreet, a party member spake unto me "I wish for an Evil Robe of the Archmagi!". The efreet grinned my obligatory BEFG for me and vanished in a swirl of smoke, reappearing momentarily with a robe cast over his arm. He promply presented it and hurriedly dove back into his bottle.
5 rounds later Rary The Enchanter appeared, mad as all hell from his interrupted bath and looking for his stolen robe.
Another common element in items of power possessed of the power of a wish is that they are not often labeled so, nor do they readily discolse such when "identified" and such. It truly becomes a case of the DM must pay attention to the words spoken by the bearer of the unknown ring, or the unidentified "Luck Blade", or whatever and present the effects of the "unknowing wish" upon the party, giving them the hint that a wish-bearing object is in their possession, and has just used up one of its charges!
Another great danger many characters fail to realize until it is far too late is the actual presence of intentionally "reversed" wishes from cursed items or locales. These "monkey's paw" wishes are dread powers that can have horrible consequences when used. Last one I DM'd for saw a recently deceased party member "returned" to the party when they wished him back to life....as a Death Knight which promptly attacked.
Generally, as long as the wish does not inherently have some potentially malicious source (cursed, fey, infernal, etc...) I look favorably when adjudicating the results based on requests that are altruistic, serve the advancement of the story, or serve to repair missteps or disasters. Careful attention in rules-lawyerly fashion indeed is still taken regarding the inclusion of such terms as "and" or "with". The prepositional phrase is the bane of wish-makers and wish granters everywhere. Blatant greed and power-mongering (see above) is dealt with accordingly.
