Subject: environment: move ignore_case into repo_config_values
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5abac96b4be55831c9aa5135ded30a907f76018c;p=thirdparty%2Fgit.git

environment: move ignore_case into repo_config_values

The 'core.ignorecase' configuration which is stored as the
global variable 'ignore_case' acts as a core filesystem
capability flag.

Move this global variable into 'struct repo_config_values' to tie it
to the specific repository instance it was read from. This reduces
global state and aligns with the ongoing libification effort.

To ensure code readability, the getter function
'repo_ignore_case()' is introduced.
