description:
Index: fixed handling of non-cacheable variables.

Previously, "e.flushed = 1;" was incorrectly used during initial length
calculations, and as a result non-cacheable variables were not flushed.
The fix is to only set "e.flushed" when evaluating values.

A similar issue in try_files was fixed in 2424:46d11bff21ef (0.7.29).
