Add note about another bad characters in salts

[dmgawel]

Characters {{ causes fail2ban error: fatal: [XXX.XXX.XXX.XXX] => Failed to template. I've added note about it.

Thanks for highlighting this as it can definitely be clarified, but I don't think that your wording is any more correct.

These CANNOT contain the characters "{%" in succession
I believe this means that { and % cannot be doubled up i.e. {{ or %% will be parsed incorrectly.

Whereas your wording could be interpreted as you cannot have {% or {{ in succession i.e. {%{% or {{{{ or {%{{ or {{{% will be parsed incorrectly.

Whatever the note gets changed to should include examples, that way you can leave out the semantics.

It's supposed to mean that {% can't appear exactly like that as a combination/group. %% shouldn't be a problem. {{ obviously would though.
