recurring msg template states number of installments - even when unlimited

file in xml/templates/message_templates/contribution_recurring_notify.html.tpl (& text.tpl)

Say
<p>

{ts 1=$recur_frequency_interval 2=$recur_frequency_unit 3=$recur_installments}

This recurring contribution will be automatically processed every %1 %2(s) for a total of %3 installment(s).

{/ts}</p>

in fact it needs to be something like

<p>{ts 1=$recur_frequency_interval 2=$recur_frequency_unit }This recurring contribution will be automatically processed every %1 %2(s){/ts}

{if $recur_installments }

{ts 3=$recur_installments}

for a total of %3 installment(s)

{/ts} {/if}

.</p>

Arguably you could be a bit cleverer about installment(s) & make it installments and change the wording more significantly if installments = 1. There is only one use case I know of for a single installment here - which is to do a delayed payment for Authorize.net - something like 'Your payment will be processed on x date' would make more sense in this single-recurring payment situation
