[PATCH v2 8/4] diff: make struct diff_flags members lowercase

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now that the flags stored in struct diff_flags are being accessed
directly and not through macros, change all struct members from being
uppercase to lowercase.
This conversion is done using the following semantic patch:
