So can we use
sscanf(buffer, " %[^\n]", command);
instead? This should allow for whitespace in the filename. Bad interface
names will be caught by the call to dev_valid_name().
(I think I'm reading the man page correctly.)
This could have the effect of making the parser way more finicky, though,
since we would allow trailing whitespace. Technically I suppose it's
legal, but it's sure hard to see on the screen.
Anybody have a better solution?
