# Enables globbing selectively on path arguments.
# Globbing is enabled on local paths (starting in '/' and './') and disabled
# on remote paths (containing ':' but not starting in '/' and './'). This is
# useful for programs that have their own globbing for remote paths.
# Currently, this is used by default for 'rsync' and 'scp'.
# Example:
# - Local: '*.txt', './foo:2017*.txt', '/var/*:log.txt'
# - Remote: user@localhost:foo/
#
# NOTE: This function is buggy and is not used anywhere until we can make sure
# it's fixed. See https://github.com/sorin-ionescu/prezto/issues/1443 and
# https://github.com/sorin-ionescu/prezto/issues/1521 for more information.
