That is probably in large part due to it being a very bad idea. As the first 
break point for that approach: what happens when a user wants to put a real 
'_' in a name?

You need to fix those scripts. Breaking because a file or directory name has 
a space in it is a warning sign about the care taken in a script and it is 
almost certain that if those scripts don't work with spaces in names, they 
will also break with other technically achievable names. There's a real 
chance that the breakage is an exploitable weakness in the scripts, with 
spaces in names being the most benign attack.
