# My `git checkout` command. My `gb` (git branch) alias emits `co` commands as part of stdout:
#
# $ gb
# co 2022-06-21 09:59:27 -0400   bug/CUI-437-achPaymentInstruction-composition
# co 2022-06-21 09:49:16 -0400 * feature/CUI-304-wire-transfer-payment
# co 2022-06-16 18:25:32 +0000   master
#
# so I can use this `co` command to quicky check out a branch from within
# a comint shell buffer in Emacs by clicking on the desired line and pressing
# Enter to execute that line as a shell command

# If arg 1 looks like a date (i.e output of my `gb` git branch alias in ../config/.alias such as 
#  co 2022-06-13 14:10:27 -0400 * feature/ADB-171-add-ADB
#  co 2022-04-01 13:32:04 +0000   master
# then throw out 3 args (date, time, zone). If next arg is *, shift it out. Then checkout
# the remaining $1 arg which is the branch name

# Else, (for example `co master` or `co master package.json`) pass all args to `git checkout`
