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."

Hmm that's quite strange. So apparently these aren't really languages, but they also don't form a subset of another language like etymology languages normally do. They're like half-languages in limbo.
