Sorry, but Kate is not able to replace Newlines, yet.
Trigraphs within comments are not warned about,
except those that would form escaped Newlines.
When newline is specified as the two-character sequence CRLF,
isolated CR and LF characters do not indicate Newlines.
They remove unnecessary whitespace, Newlines, and comments, and shorten variable names, and
thus reduce the size of the documents that your site publishes.
If there are no Newlines in a subject string, or no occurrences of ^ or $
in a pattern, setting multiline has no effect.
If there are no Newlines in a subject string, or no occurrences of ^ or $

Which characters are interpreted as Newlines is controlled by the options passed to a compiling function
or by a special sequence at the start of the pattern, as described in section Newline Conventions earlier.
