Hmmm... there's a tradeoff. Verbose error messages are very useful for the beginner, or for obscure error messages that happen very rarely. Terse error messages are more efficient, especially for errors that occur often.
Compare "permission denied" to "Your currently active user id, 'im14u2c', does not have write permission on the file '/tmp/xyzpdq'. This file is owned by 'im14u2c', but the user write permission bit on the file is not set. Please consult the 'chmod' man page."
The latter is very friendly to a new user. Just awesome. But, it would get real old real quick. And, depending on the context, the advice implied by the error message (in this case, chmod +w is implied) might be wrong advice. (For example, what if the file in question is an RCS controlled file that isn't checked out?) Perhaps a settable "user expert level" needs to be specified to indicate how chatty the system should be?
