This makes the test more verbose. Specifically, the

numbers matching <pattern>. The number matched against is
simply the running count of the test within the file.

--debug::
This may help the person who is developing a new test.
It causes the command defined with test_debug to run.

This causes the test to immediately exit upon the first

+For an individual test suite --run could be used to specify that
+only some tests should be run or that some tests should be
+excluded from a run.
+
+The argument for --run is a list of individual test numbers or
+ranges with an optional negation prefix that define what tests in
+a test suite to include in the run. A range is two numbers
+separated with a dash and matches a range of tests with both ends
+been included. You may omit the first or the second number to
+mean "from the first test" or "up to the very last test"
+respectively.
+
+Optional prefix of '!' means that the test or a range of tests
+should be excluded from the run.
+
+If --run starts with an unprefixed number or range the initial
+set of tests to run is empty. If the first item starts with '!'
+all the tests are added to the initial set. After initial set is
+determined every test number or range is added or excluded from
+the set one by one, from left to right.
+
+Individual numbers or ranges could be separated either by a space
+or a comma.
+
+For example, to run only tests up to a specific test (21), one
+could do this:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='1-21'
+
+or this:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='-21'
+
+Common case is to run several setup tests (1, 2, 3) and then a
+specific test (21) that relies on that setup:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='1 2 3 21'
+
+or:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run=1,2,3,21
+
+or:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='-3 21'
+
+As noted above, the test set is built going though items left to
+right, so this:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='1-4 !3'
+
+will run tests 1, 2, and 4. Items that comes later have higher
+precendence. It means that this:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='!3 1-4'
+
+would just run tests from 1 to 4, including 3.
+
+You may use negation with ranges. The following will run all
+test in the test suite except from 7 up to 11:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='!7-11'
+
+Some tests in a test suite rely on the previous tests performing
+certain actions, specifically some tests are designated as
+"setup" test, so you cannot _arbitrarily_ disable one test and
+expect the rest to function correctly.
+
+--run is mostly useful when you want to focus on a specific test
+and know what setup is needed for it. Or when you want to run
+everything up to a certain test.
