fc and the verbose mode

[isabella parakiss]

fc activates the verbose mode to print the commands as they're read by
the parser and uses unwind_protect_int to restore it.

This is a good idea but there are a few problems with it:
1. it prints the DEBUG trap, which I didn't expect
2. it's impossible to use fc to turn on/off the verbose mode
   ( well, you can, but it's lost as soon as the command ends )

Is it possible to print the commands without activating that mode?
