some problem with "delete" command

[howaboutuser]

1. If global function or unit is rewrited, then use "delete" to restore the function or unit, the name doesn't delete in list command.

sin()=1 N=1 delete sin delete N list

Variables: Name Value ans 1 ans2 '1'

Functions: sin

Units: newton

2. If variable and function have same name, it can not specify which to delete. (delete temp() not work)

temp=1 temp()=2 delete temp list

Variables: Name Value ans '2' ans2 1

Functions: temp
