tests: use NO_CHECK_EOF for fragments having intentional error
Some test scripts are excluded in test-check-module-imports.t, because
import-checker.py reports that code fragments embedded in these test
scripts have syntax error. But these syntax error is intentional.
This patch uses NO_CHECK_EOF instead of EOF as heredoc limit mark for
such fragments, in order to make import-checker.py ignore
them. NO_CHECK_EOF limit mark tells import-checker.py that this code
fragment should be ignored, via testparseutil.py.

'''measure performance of Mercurial commands Using ``hgperf`` instead of ``hg`` measures performance of the target Mercurial command. For example, the execution below measures performance of :hg:`heads --topo`:: $ hgperf heads --topo All command output via ``ui`` is suppressed, and just measurement result is displayed: see also "perf" extension in "contrib". Costs of processing before dispatching to the command function like below are not measured:: - parsing command line (e.g. option validity check) - reading configuration files in But ``pre-`` and ``post-`` hook invocation for the target command is measured, even though these are invoked before or after dispatching to the command function, because these may be required to repeat execution of the target command correctly.
