Add proc subst_vars, an alias of subst -nobackslashes -nocommands.
I've used tailcall to implement this:
...
proc subst_vars { str } {
tailcall subst -nobackslashes -nocommands $str
}
...
but I found that this also works:
...
proc subst_vars { str } {
return [uplevel 1 [list subst -nobackslashes -nocommands $str]]
}
...
I've found other uses of subst that don't add "-nobackslashes -nocommands",
but really only use subst to do variable substitution. Also use subst_vars in
those cases.
Tested on x86_64-linux.
