[PATCH] diff.c: locate_size_cache() fix.
This fixes two bugs.
- declaration of auto variable "cmp" was preceeded by a
statement, causing compilation error on real C compilers;
noticed and patch given by Yoichi Yuasa.
- the function's calling convention was overloading its size
parameter to mean "largest possible value means do not add
entry", which was a bad taste. Brought up during a
discussion with Peter Baudis.
