Johannes Sixt 8c64bc9420 t3404-rebase-interactive: test abbreviated commands
Make sure that each short command is tested at least once. To
not exacerbate the runtime of the test script, do not add new
tests, but modify existing ones according to these criteria:

- The test does not have a prerequisite.
- The 'git rebase' command is not guarded by test_must_fail.

The pick commands are optional in the FAKE_LINES variable, but
when used, they do end up in the insn sheet. Test them, too.

# Helper functions used by interactive rebase tests.
# After setting the fake editor with this function, you can
#
# - override the commit message with $FAKE_COMMIT_MESSAGE
# - amend the commit message with $FAKE_COMMIT_AMEND
# - check that non-commit messages have a certain line count with $EXPECT_COUNT
# - check the commit count in the commit message header with $EXPECT_HEADER_COUNT
# - rewrite a rebase -i script as directed by $FAKE_LINES.
# $FAKE_LINES consists of a sequence of words separated by spaces.
# The following word combinations are possible:
#
# "<lineno>" -- add a "pick" line with the SHA1 taken from the
# specified line.
#
# "<cmd> <lineno>" -- add a line with the specified command
# ("pick", "squash", "fixup", "edit", "reword" or "drop") and the
# SHA1 taken from the specified line.
#
# "exec_cmd_with_args" -- add an "exec cmd with args" line.
#
# "#" -- Add a comment line.
#
# ">" -- Add a blank line.
