pub fn system_config_for(variables: &[(OsString, OsString)]) -> Option<PathBuf>Expand description
What:
The system configuration path the Git a child would run reads, learned from the forward-target variable the wrapper
puts in every child’s environment.
Why:
None (no variable, no identity, no answer) makes the readers decline whenever the system file would be read.
In TS you’d write (pseudocode):
const path = systemConfigFor(env); // undefined: unknown
