memo

#prefix = 
#bindir = $(prefix)/bin
#gitexecdir = bin/git-core
#sysconfdir = sys/lib/git
#template_dir = sys/lib/git/templates
#mandir = $(prefix)/sys/man

fix-cc

git grep -n '{[   ]*OPTION_' ':*.c'
git grep -ni '	struct.*[a-z0-9_][ 	]*=[ 	]*{'
git grep -E '     \.[a-zA-Z0-9]+ ?= ?'

現在残っている { OPTION_XXX ... } で初期化のあるオプションは、ほとんどの場合

// config.c
#define OPT_INTEGER_VALUE(...)
#define OPT_STRING_VALUE(...)
#define OPT_CALLBACK_VALUE(...)

のように_VALUEがあれば対応できそう。
