+'bidi-import'::
+ The fast-import commands 'cat-blob' and 'ls' can be used by
remote-helpers
+ to retrieve information about blobs and trees that already exist in
+ fast-import's memory. This requires a channel from fast-import to the
+ remote-helper.
+ If it is advertised in addition to "import", git establishes a pipe from
+ fast-import to the remote-helper's stdin.
+ It follows that git and fast-import are both connected to the
+ remote-helper's stdin. Because git can send multiple commands to
+ the remote-helper it is required that helpers that use 'bidi-import'
+ buffer all 'import' commands of a batch before sending data to
fast-import.
+ This is to prevent mixing commands and fast-import responses on the
+ helper's stdin.
