post: fix indendation/brace confusion

The post.c code is missing braces around the pass case, and as a
result, the diagnostic function will post both fail and pass for
a failed test.  The reason for this bug is probably the incorrect
indentation used, so when reading the code it seems like there
are proper braces.

Indent the code to the correct depth and put proper braces around
the "else" branch of the "if" statement.
