Document INNER_TESTSUITEFLAGS, drop leading space

[Ralf Wildenhues]

Hello,

I found this very helpful while debugging the template test inside the
low max_cmd_len test.  Any reasons against applying it?

Thanks,
Ralf

        * README: Document INNER_TESTSUITEFLAGS.
        * tests/cmdline_wrap.at (Run tests with low max_cmd_len):
        When using INNER_TESTSUITEFLAGS on the testsuite invocation,
        drop leading space after "-k libtool", so that the user may
        further limit the set of tests to be run.

+Some tests, like the one exercising max_cmd_len limits, make use of this
+to invoke the testsuite recursively on a subset of tests.  For these
+tests, the variable INNER_TESTSUITEFLAGS may be used.  It will be
+expanded right after the `-k libtool', without separating whitespace,
+so that further limiting of the recursive set of tests is possible.
+For example, to run only the template tests within the max_cmd_len, use
+  gmake check-local TESTSUITEFLAGS="-v -x -k max_cmd_len \
+                     INNER_TESTSUITEFLAGS=',template -v -x'"

 send the file `tests/testsuite.log' to the bug report mailing list,
