Actually, having given it a little more thought, it appears that the space
character (which my posted code properly accounts for) is the only
character, apart from the dot itself, which is permitted in a file name
but not permitted in a file extension.
I just renamed a file by placing a space in the extension and my WindowsXP
Pro system let me do it without complaining. Well, it did complain, but only
with a warning that changing a file name extension may make the file
unusable (I had renamed a ".txt" file to ".t xt", but I could open it fine
from Notepad).
