Extremely vaguely, I remember someone (possibly at MSFN) had patched some system file related to the Open/Save dialogs. It may well be this Common Dialogs library (comdlg32.dll). Scouring through my system I found this library with the very same version number as the one on the Windows installation CD (4.72.3510.2300) but of a strikingly shorter size: 172,032 bytes vs 176,128 bytes on CD.
I must have had that file installed for ages but for the life of me I can't remember how or where I got it from. Thing is, the name field width in my version is quite large, just as you'd like it (or close enough), TmEE. That is unless those values are written somewhere in the registry.
Oddly enough, the aforementioned library only presents a ListBox control in its Dialog resources, while in Details view the Open/Save dialog uses a ListView control. This means, for a change in appearance one should disassemble the code and find where the ListView parameters are stored/changed and alter them accordingly. Again, unless all this is stored in the registry, which I do not know.
Here's a screenshot of an Open File dialog as it pops up unmodified on my 98SE system:
