I was about to say "Let's not do this until some caller needs it",
implicitly assuming that we do not let global=NULL to signal that
the caller is interested only in XDG, but I checked and we do check
the NULL-ness of global, so it is consistent to do so for xdg. The
change makes very good sense.
I wouldn't have had to spend the time to dig, if the log message
justified it that way, instead of having "actually not needed"
comment there ;-)
home_config_paths(): let the caller ignore xdg path
The caller can signal that it is not interested in learning
the location of $HOME/.gitconfig by passing global=NULL, but
there is no way to decline the ptah to the configuration
file based on $XDG_CONFIG_HOME.
Allow the caller to pass xdg=NULL to signal that it is not
interested in the XDG location.
or something, perhaps?
