No, the idea is to make some parameters (see list below) safer to use.

Particularly, I'd like to make Andy Bakun's open/close command patch
safer as well so I can make use of it. The open/close command patch is
very useful, and tons safer than the 'magic script' parameter...

The parameters I'm trying to make safer to use are:

 - root preexec
 - root postexec
 - preexec
 - postexec
 - print command
 - open command (from Andy Bakun's patch)
 - close command (from Andy Bakun's patch)

BTW, I'll code this feature, just like I did with 'source environment';
I just want to know what method is preferred.

As I think about it I'm beginning to settle for making the code that
implements those parameters call safe_quote() prior to calling
string_sub() directly; as for the % tokens substituted by
standard_sub_basic(), oh well.
