[aur-dev] Fix for some plural strings

[Safa Alfulaij]

Hello.
There is "It must be between %s and %s characters long" and "Your password
must be at least %s characters." besides the "View all %n comments".
Please, English differs from other languages. If a string don't need to
pluralize in English, It will need to pluralize in other languages.
About "View all %s comments", There is no problem if you patch it as I
sent. There is already an if statement that checks if $count is higher than
10. Hard-coding "View all %s comment" don't give any problems as it won't
be used.

Regards,
Safa
