The current test does not exactly test for unset DOCS, because it also |
| 2 |
evaluates as true if the variable has attributes. Such attributes can |
| 3 |
be defined even for an unset variable. |

|

Therefore test the output of declare -p for presence of an = sign |
| 6 |
instead, which indicates that a value has been assigned to the |
| 7 |
variable (bug 710076 comment #2). |
