Vendor cd functions for why did I do this

cd-vendor.sh

# To be sourced in either zsh or bash
# cdv works better if you use zsh and cd is synonymous with pushd

# vendor_subpath looks for any vendor directory in the current directory and in any directory above it. If found, it
# will search that directory first for an exact match and then the shortest inexact match for the path given (arg 1).
#
# E.g., vendor_subpath foo/bar will search first for an exact vendor/foo/bar directory. If none is found, it will then
# try to find vendor/*foo/bar* and pick the shortest.

# popv will change the current directory to the directory containing the vendor directory if currently in a vendor
# directory. This is only useful if you don't use popd instead or want very specifically to return to that directory and
# not a prior, different directory.
