If I were applying, I would capitalize the commit subjects and fix the typos in the commit logs, e.g., s/the this/the/ s/the the/that the/ s/short coming/shortcoming/ s/seperate/separate/ s/bid endian/big endian/ s/were appropriate/where appropriate/ s/name form/name from/ etc. git am also complains about space before tab whitespace errors. And it adds a few lines >80 chars.
