## vim:ft=zsh
#
# This function is the common guts of the gen-applied-string /
# gen-unapplied-string / set-patch-format dance of several backends.
#
# Parameters:
# $1 - name of an array parameter to be the argument to gen-applied-string
#      (patches in reverse order)
# $2 - name of a parameter to store the applied-string in
# $3 - name of an array parameter to be the argument to gen-unapplied-string
#      (patches in order)
# $4 - name of a parameter to store the unapplied-string in
# $5 - context argument for use in zstyle getters
# $6 - name of a parameter to store a patch-format format string in
# $7 - name of an assoc parameter with extra $hook_com key-value pairs for the
#      set-patch-format hook invocation, or '' for none
# $8 - name of a function that sets $reply to extra arguments for the patch-format zformat call, or '' for none
# $9 - name of an assoc parameter with extra $hook_com key-value pairs for the
#      gen-applied-string & gen-unapplied-string hook invocations, or '' for none
#
# The expanded patch-format string is returned in $REPLY.
#
# Output:
# - $hook_com is overwritten and the keys 'applied', 'applied-n',
#   'unapplied', 'unapplied-n', 'all-n' are set.
