Unix install script fails on some machines with "curl: (3) bad range specification in URL position"

Error when running ./unix/seutp.sh:

grep had been aliased on student machine: grep: aliased to grep --color=auto --exclude-dir={.bzr,CVS,.git,.hg,.svn,.idea,.tox}

Should instead use /usr/bin/grep and /usr/bin/sed to protect against this in install shell scripts.

Second thought it's probably not an aliased grep, the error is coming from curl from bad input and the grep is just to exclude files.

Several issues could cause the sed command to incorrectly parse the API response, unclear with limited information.

Will keep open if someone else has this but do not want to update install scripts since hardcoding grep and sed could be equally annoying and faulty.

Homebrew users (particularly on macos) can now install with:

brew tap camerondurham/tap
brew install camerondurham/tap/ch

Verified the existing install script in my darwin-arm64 environment (M1 MacBook Air) and darwin-amd64 (Intel MacBook Pro).
