Perform an operation on each config variable in a given config backend,
matching a regular expression.
This behaves like git_config_foreach_match except that only config
entries from the given backend entry are enumerated.
The regular expression is applied case-sensitively on the normalized form of
the variable name: the section and variable parts are lower-cased. The
subsection is left unchanged.
@param backend where to get the variables from
@param regexp regular expression to match against config names (can be null)
@param callback the function to call on each variable
@param payload the data to pass to the callback
