 get_if_var() normalizes IF part in the variable name before eval:

 |       _if=$1
 |       _punct=". - / +"
 |       for _punct_c in $_punct; do
 |               _if=`ltr ${_if} ${_punct_c} '_'`
 |       done

 while list_vars ifconfig_${_if}_alias[0-9]\* does not.

 I think this breaks the following configuration, for example:

 ifconfig_bge0_name="ext.1"
 ifconfig_ext_1="inet 192.168.0.1/24"
 ifconfig_ext_1_alias0="inet 192.168.1.1/24"
