When bisecting a performance regression using a config file,
`./bisect_regression --config my_perf.conf` for example, the
config file can contain Codespeed configuration which would
instruct the 'aggregate.perl' script called by the 'run'
script to output results in the Codespeed format and maybe
to try to send this output to a Codespeed server.
This is unfortunate because the 'bisect_run_script' relies
on the regular output from 'aggregate.perl' to mesure
performance, so let's disable Codespeed output and sending
results to a Codespeed server.

If you do something like
- git add .
- git status
- git commit
- git show (or git diff HEAD)
one would expect to have analogous output from git status and git show
(or similar diff-related programs). This is generally not the case, as
git status has hard coded values for diff related options.
With this commit the hard coded settings are dropped from the status
command in favour for values provided by git_diff_ui_config.
What follows are some remarks on the concrete options which were hard
coded in git status:
diffopt.detect_rename
Since the very beginning of git status in a3e870f2e2 ("Add "commit"
helper script", 2005-05-30), git status always used rename detection,
whereas with commands like show and log one had to activate it with a
command line option. After 5404c116aa ("diff: activate diff.renames by
default", 2016-02-25) the default behaves the same by coincidence, but
changing diff.renames to other values can break the consistency between
git status and other commands again. With this commit one control the
same default behaviour with diff.renames.
diffopt.rename_limit
Similarly one has the option diff.renamelimit to adjust this limit for
all commands but git status. With this commit git status will also honor
those.
diffopt.break_opt
Unlike the other two options this cannot be configured by a
configuration option yet. This commit will also change the default
behaviour to not use break rewrites. But as rename detection is most
likely on, this is dangerous to be activated anyway as one can see
here:

It is possible to configure 'less', the pager, to use an alternate
screen to show the content, for example, by setting LESS=RS in the
environment. When it is closed in this configuration, it switches
back to the original screen, and all content is gone.
It is not uncommon to request that the output remains visible in
the terminal. For this, the option --no-pager can be used. But
it is a bit cumbersome to type, even when command completion is
available. Provide a short option, -P, to make the option more
easily accessible.

When formatted as a man page, 1st section header is always in upper
case even if we write it otherwise. Make all 1st section headers
uppercase to keep it close to the final output.
This does affect html since case is kept there, but I still think it's
a good idea to maintain a consistent style for 1st section headers.
Some sections perhaps should become second sections instead, where
case is kept, and for better organization. I will update if anyone has
suggestions about this.
While at there I also make some header more consistent (e.g. examples
vs example) and fix a couple minor things here and there.

the constants 20 and 40. Switch one use of 20 with a format specifier
for a hex value to use the hex constant instead, as the original appears
to have been a typo.
At this point, avoid converting the hard-coded use of SHA-1 to use
the_hash_algo. SHA-1, even if not collision resistant, is secure in the
context in which it is used here, and the hash algorithm of the repo
need not match what is used here. When we adopt a new hash algorithm,
we can simply adopt the new algorithm wholesale here, as the nonce is
opaque and its length and validity are entirely controlled by the
server. Consequently, defer updating this code until that point.
