# When trying to match a unit name with certain special characters in its name (i.e
# foo\x2dbar:01) they get (un)escaped by bash along the way, thus causing any possible
# match to fail.
# The following condition solves two cases:
# 1) We're trying to complete an already escaped unit name part,
# i.e foo\\x2dba. In this case we need to unescape the name, so it
# gets properly matched with the systemctl output (i.e. foo\x2dba).
# However, we need to keep the original escaped name as well for the
# final match, as the completion machinery does the unescaping
# automagically.
# 2) We're trying to complete an unescaped (literal) unit name part,
# i.e. foo\x2dba. That means we don't have to do the unescaping
# required for correct matching with systemctl's output, however,
# we need to escape the name for the final match, where the completion
# expects the string to be escaped.
