652 This can cause problems when variable modifiers are used.
656 then assign the output from the child's standard output to the variable.
663 In other contexts (most variable modifiers, string literals in conditions),
671 If the variable name consists of only a single character
676 If the variable name contains a dollar, the name itself is expanded first.

1409 The general format of a variable expansion is:
1412 .D1 Ic \&${ Ar variable\| Oo Ic \&: Ar modifier\| Oo Ic \&: No ... Oc Oc Ic \&}
1419 A list of indirect modifiers can be specified via a variable, as follows:
1425 .Ic \&${ Ar variable Ic \&:${ Ar modifier_variable Ic \&} Oo Ic \&: No ... Oc Ic \&}
