  docs: document --textconv diff option

This has been there since textconv existed, but was never
documented. There is some overlap with what's in
gitattributes(5), but it's important to warn in both places
that textconv diffs probably can't be applied.

  test: skip clean-up when running under --immediate mode
  "branch -d" can remove more than one branches

Some tests try to be too careful about cleaning themselves up and
do

    test_expect_success description '
        set-up some test refs and/or configuration &&
        test_when_finished "revert the above changes" &&
	the real test
    '

Which is nice to make sure that a potential failure would not have
unexpected interaction with the next test. This however interferes when
"the real test" fails and we want to see what is going on, by running the
test with --immediate mode and descending into its trash directory after
the test stops. The precondition to run the real test and cause it to fail
is all gone after the clean-up procedure defined by test_when_finished is
done.

Update test_run_ which is the workhorse of running a test script
called from test_expect_success and test_expect_failure, so that we do not
run clean-up script defined with test_when_finished when a test that is
expected to succeed fails under the --immediate mode.

If the bottom of a mergeinfo range is a commit that maps to a git root
commit, then it doesn't have a parent.  In such a case, use git commit
range "$top_commit" rather than "$bottom_commit^..$top_commit".

If a svn:mergeinfo range starts at a commit that was converted as a
git root commit (e.g., r1 or a branch that was created out of thin
air), then there is an error when git-svn tries to run

    git rev-list "$bottom_commit^..$top_commit"

because $bottom_commit (the git commit corresponding to r1) has no
parent.

Currently start/restart does not generate any configuration files for
spawning a new instance.  This means that

  $ git instaweb --http=<server> --start

might pick up stale 'httpd.conf' file for a different web server
(e.g. for default lighttpd when requesting apache2).

This commit changes that, and makes git-instaweb generate web server
config file and/or gitweb config file if don't exists.

This required naming config files after the name of web server
(alternate solution would be to somehow mark for which web server was
config file generated).

Note that web servers that embed configuration in server script file,
namely webrick and plackup, and which delete "$conf" in their *_conf
function, would have their config (server script) always regenerated.

Note: this commit introduces a bit of code repetition (but only a few
lines).

As a nice side-effect now the order of parameters does not matter:

  $ git instaweb --httpd=apache2 --start

is now (after this patch) the same as

  $ git instaweb --start --httpd=apache2

Before this commit --start, --stop, --restart (and their subcommand
versions start, stop, restart) exited immediately.

This is preparatory work for making start/restart check that correct
configuration is set up; this change was required to have access in
start_httpd to requested web browser etc.

  t7810: avoid unportable use of "echo"

Michael J Gruber noticed that under /bin/dash this test failed
(as is expected -- \n in the string can be interpreted by the
command), while it passed with bash.  We probably could work it
around by using backquote in front of it, but it is safer and
more readable to avoid "echo" altogether in a case like this.
