[Newcomer PATCH] log-tree.c: Supress Wsign-compare-warning

[Fernando Gouveia Lima fernandolimabusiness@gmail.com]

From: Fernando Gouveia Lima <fernandolimabusiness@gmail.com>

Two comparisions between int and size_t, and int and unsigned long int
cause warning sign compare to fire.

Avoid this by changing the type of variable "i" in add_ref_decoration() to unsigned long int and
casting the variable "filename->len" to int in fmt_output_subject().

This is my first contribution and i got this idea on the Microproject
page. I hope this is the first of many contributions to the git
community :).
