[PATCH v3 3/5] enter_repo: allow .git files in strict mode

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Strict mode is about not guessing where .git is. If the user points to a
.git file, we know exactly where the target .git dir will be.

This is needed even in local clone case because transport.c code uses
upload-pack for fetching remote refs.
