FileSystemLoader: {% import foo/test %} fails if there are templates 'foo' and 'foo/test'

[praiskup]

Consider the FileSystemLoader([dir1, dir2]), where dir1 containers foo template, while dir2 contains directory foo with file test.

Expected Behavior

The env.get_template('foo/test') should return proper template.

Actual Behavior

The env.get_template('foo/test') raises
-> IOError: [Errno 20] Not a directory: 'dir1/foo/test'

Full Traceback

IOError: [Errno 20] Not a directory: 'dir1/foo/test'
>>> from jinja2 import FileSystemLoader, Environment
>>> loader = FileSystemLoader(['dir1', 'dir2'])

Interesting.. seems like open_if_exists should check for ENOTDIR as well.

[ThiefMaster]

Sounds like a good candidate for a PR to fix it (against 2.10-maintenance)

[praiskup]

Testcase is needed? (btw. yes, ignoring ENOTDIR helps..)
