Re: [PATCH 3/7] grep: typesafe versions of grep_source_init

Jonathan Tan [off-list ref] writes:

grep_source_init() can create "struct grep_source" objects and,
depending on the value of the type passed, some void-pointer parameters have
different meanings. Because one of these types (GREP_SOURCE_OID) will
require an additional parameter in a subsequent patch, take the
opportunity to increase clarity and type safety by replacing this
function with individual functions for each type.

Nice clean-up.
