I was readingmakeunicodedata.py and found a small issue that leads to a bit of wasted space in theunicodedata module. Thiscode:

try:i=decomp_data.index(decomp)exceptValueError:i=len(decomp_data)decomp_data.extend(decomp)decomp_size=decomp_size+len(decomp)*2

will always take the exception path because bothdecomp_data anddecomp are lists of ints, so theindex call always raises. I think it was copy-pasted from some similar code afew lines up which however is about a lists of strings and a string, so it works there.

I will prepare a PR. The space saving isn't gigantic (about 4.5kib) but as it stands the code is confusing.
