| Subject: | Configuration: Setting a variable to q[ ] sets variable to q[]. |
When using the `o conf init ${VARIABLENAME}` command, such as when
selecting a tar program, if the user enters simply a space, or three, or
three thousand (the former two tested, the latter merely presumed) the
shell ignores the setting and saves the variable as q[]. For variables
such as 'tar', q[ ] means something rather different from q[].
