[GSOC PATCH 0/2] builtin/fmt-merge-msg: remove dependency on global variables and 'the_repository'

[Ayush Chandekar <ayu.chandekar@gmail.com>]

The aim of this patch series is to remove the definition '#define USE_THE_REPOSITORY_VARIABLE'
from "builtin/fmt-merge-msg.c" by removing global variable 'merge_log_config' and the global 
'the_repository'

This patch series contains two patches:

1 - Remove the global varaible 'merge_log_config' and add a function 'adjust_shortlog_len()'
    in fmt-merge-msg.{c,h} to replicate the variable's usage.

2 - Remove the dependency of 'the_repository' in "builtin/fmt-merge-msg.c", allowing the removal
    of the definition '#define USE_THE_REPOSITORY_VARIABLE'. Also add a test to make sure that
    "git fmt-merge-msg -h" can be called with repository being NULL.

Ayush Chandekar (2):
  environment: remove the global variable 'merge_log_config'
  builtin/fmt-merge-msg: stop depending on 'the_repository'
