The problems with that are, the output here is in the Admin log, and as you know that can be a whole range of possible outputs. So I don't think you'd want to do a utf8_wordwrap on everything output to the log.

On top of that, the ACP is just not at all conducive to CSS based handling of long file names, because that requires an enclosing element of fixed width, and the ACP is all about tables, with variable width table cells, all of which have undefined sizes.

And since you have to choose a fixed width for the one element, it's gonna wind up seeming too small on wide screens, considering that you have to also accommodate smaller screens (until responsive kicks in). Also, the element you have fix the width on, is the one element that should be most variable in the table, as it is the one containing the most information.

Isn't it OK this one time here, since it's only just the admin log we're talking about here.
