leading/trailing newline validation should not check the line numbers

In the web UI of Zanata, the validation of "leading/trailing newline (\n)"
is described as "check for consistent leading and trailing newline (\n)".
But actually, besides checking the leading/trailing newline, the validation will also check whether the line numbers of the source string and translation string are exactly same. If the leading/trailing newline are same, but line numbers are not same, it will report error or warning.

I think, the validation of "leading/trailing newline (\n)" should not check the line numbers. If it's needed to check the line numbers, it's better to separate into two kinds of validations: leading/trailing newline (\n) and same line numbers. Separating into two kinds of validations will help users to config.
