Multi-line statements broken in custom SQL

[Aymeric Augustin]

After upgrading to Django 1.5 alpha, custom SQL files containing multi-line statements aren't loaded any longer.

I get the following error:

Failed to install custom SQL for sessions.Session model: syntax error at or near "sessions_session"
LINE 1: ...E INDEX unique_active_session_user_idON sessions_s...

This regression was introduced in 423244bc6b670abc2b7d6896add5c1baf0b4ef2a.

The problem lies in the _split_statements added by this commit. It strips whitespace and joins consecutive lines without keeping a space:

>>> multi_line_sql = """
... CREATE UNIQUE INDEX unique_active_session_user_id
...     ON sessions_session(user_id)
...     WHERE closed_at IS NULL;
... """
>>> from django.core.management.sql import _split_statements
>>> _split_statements(multi_line_sql)
[u'CREATE UNIQUE INDEX unique_active_session_user_idON sessions_session(user_id)WHERE closed_at IS NULL;']
