When uploading files with a destination filename that contains slashes, only the part of the name after the slash is used. The other part of the name is removed when pressing upload file. There should be a warning about the changed name, like the warning when spaces are changed to underscores.

Hmm, seems to me there's still a bit of a problem with how the 'destination filename' box is treated compared to the originally-reported upload filename.
Since the reported upload filename sometimes includes a path, calling wfBasename() to strip the path components is a fairly sane way to treat it, and we wouldn't want to give a warning about it at that level.
The destination name, though, will usually be one of:
or
In the former case, there shouldn't be any /s or \s since it's already been stripped clinet-side. In the latter case, the user might have typed a / or \ deliberately.
For an example, I tried setting a destination filename to "Graphite-half-1680 (OS/X).png" and got told the filename was being stripped to "X).png".
Better behavior might be to take the given destination filename and just strip out any / and \ chars as we do for : and other illegals, giving in this case "Graphite-half-1680 (OS-X).png"
