Zsh may be configured such that ">>" will error if the file doesn't exist (`setopt noclobber`). 

tput is error-prone and may not be needed, since all the formatting
codes used are standard across all types of terminals.

* gitfast: use $OSTYPE again

In the last update to upstream this was reverted:

 a56eac7a

 (Use OSTYPE instead of uname whenever possible for better speed. (#5496))

No need to set and unset a variable we use once.

* gitfast: add script to update from upstream

This would make easier the process of updating, and also not miss our
patches.

installer: fix, refactor and add installer arguments

tput may throw errors on invalid $TERM values, for example.
This shorthand syntax allows for that as well as for if tput
doesn't exist.

Supposed to be POSIX-compatible. Proved to work in dash, yash and whatever
alpine uses. See https://unix.stackexchange.com/a/371873

This facilitates testing of changes to the core installation code: you'll be
able to do a roundtrip test of install and uninstall using the working code on
your branch.

Controlled by passing $REPO and $BRANCH environment variables to install.sh.

This changes the behavior to default to the binary found first in $PATH,
then checking it's actually in the shells file (/etc/shells).

If that fails go back to the previous behavior, but actually check that
the path obtained exists in the filesystem.

Guard clauses are if constructs that return early if there is an error
that prevents continuing. This way there isn't a big nesting of if
expressions.

Otherwise we risk a situation where a full path to `zsh` is commented, i.e.:

    #/usr/local/bin/zsh

This replaces the currently running process with the new one using `exec`
instead of creating a new process. This way, when the user `exit`s out of
the new shell it will not pop them back into the shell from which ohmyzsh
was installed from.

This will allow us to use tab stripping heredocs with `<<-'.
