[RFC PATCH v2 3/7] config: correct bad boolean env value error message

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



An incorrectly defined boolean environment value would result in the
following error message:

bad boolean config value '%s' for '%s'

This is a misnomer since environment value != config value. Instead of
calling git_config_bool() to parse the environment value, mimic the
functionality inside of git_config_bool() but with the correct error
message.
