[PATCH 1/3] t3700: note a .gitignore matching fault

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

.gitignore support both positive and negative patterns. One may negate
the other. Current code works well if both patterns target files in
the same directory.

When a pattern targets a directory and an opposite pattern targets
some files/directories within that directory, we need to descend in
the directory until we're clear which ones are matched and which are
not.

excluded_from_list() fails to handle this case. It too eagerly decides
the fate of the whole directory without looking further in.
