     1220        * inode via multiple hardlinks or different names.  Specifically,
     1221        * Apache will be able to read both names if it was first looked
     1222        * up (by anyone!) via .htaccess, and neither if it was first
     1223        * looked up via foo.

     1226        * three characters, so it takes O(3) operations.  If this code
     1227        * is extended to all static-cat extensions, we'll want to do
     1228        * some clever hashing using gperf here.
