Subject: [patch] trans-mem: Require parentheses when parsing transaction expressions.

patch2 fixes parsing of transaction expressions, so that two txn
expressions that are part of a single expression do not get treated as
nested txns anymore, but become two separate ones (see test case).
Approved off-line by Richard Henderson, but I'll run tests again
tomorrow just to be sure.

patch1 is a trivial fix for one of the previous test cases (add cleanup
for dump tree, fix a typo in a comment).
