#66526: Port space command ignores hardlinks in it's total size calculations

 I'm using `port space --units MB installed | sort -n # MacPorts: list
 ports by size`

 I get `523.30 MB git @2.39.0_0`

 This is incorrect since git has ~140 files 3.2m each (or physical 1.6m,
 not sure why there is such a big discrepancy here for a single file) that
 are actually hardlinks to a single file

 The `port space` command should calculate the size of a file as `file
 size/count of hardlinks` and then sum this up to get the size of a port
 instead of summing up `file size`'s as is
