Note that the `HOMEBREW_FORCE_BREWED_` vars are automatically set if the system `git` and `curl` are too old. Drop mention of `HOMEBREW_GIT` which isn't user-settable.
Work around ronn's inability to nest indents within list items by modifying its output to add a line break and indent after lines ending with a colon that aren't a list item's first line. This allows `brew.1.md.erb` to join the commands' help text without extra line breaks, which avoids the issue where kramdown was turning any command specs containing pipe characters into tables in the HTML output.
Rather than relying on a `HOMEBREW_FORCE_BOTTLE` variable (which ends
up doing silly things like forcing bottle usage even when options are
provided) instead handle this at the `or_later` bottle detection
level so on prerelease versions of macOS any bottle looks like an
`or_later` bottle (unless various environment variables are set).

This does the equivalent of always passing `--force-bottle`. This will
be enabled by default on Mojave to allow people to avoid building
everything from source until our porting and bottling is a bit further
along.
Because of this messing with the user's path:

brew uses /usr/bin/git over brewed git, even when the former is
problematically old.
There may also be other reasons a user prefers to use brewed git.
There was already a HOMEBREW_FORCE_BREWED_CURL option and a
HOMEBREW_SYSTEM_CURL_TOO_OLD check to set it. This mostly copies those
to implement HOMEBREW_FORCE_BREWED_GIT & HOMEBREW_SYSTEM_GIT_TOO_OLD.

- Document ilovezfs as the official lead maintainer of
Homebrew/homebrew-core. This is a role he's been doing unofficially
(and brilliantly) for a while and explicit documentation of power
structures makes it easier for non-Homebrew-maintainers to understand.
- Document the contents of some of Homebrew's subdirectories for people
clicking around in the GitHub UI looking to contribute.
- Remove update bug mention from README. Enough time has passed that we
can remove this disappointment.
- only document HOMEBREW_* variables in the manpage (although still
read from all the original environment variables).
- resort manpage environment variables in alphabetical order
- check the original path for trailing slashes
