Thread:User talk:CodeCat/Etymology languages' parents

CodeCat, you edited Module:etymology and said: "Etymology languages' parents are always languages (or another etymology language! See the data module!) but never families"

This edit broke a few entries that were just fine before:
 * Pérgamo -> contains the code "pregrc" (parent: "qfa-sub" = substrate)
 * balsa -> contains the code "und-ibe" (parent: "qfa-sub" as above)
 * zarza -> contains the code "und-ibe"
 * zurrapa -> contains the code "und-ibe"
 * ܚܡܘܪܬܐ -> contains the code "MIr." (parent: "ira" = Iranian family)
 * पुस्तक -> contains the code "MIr."
