Preserve Existing Line Breaks

When the Preserve Existing Line Breaks option is on, the VLISP formatter inserts new lines whenever a new line is detected in the text it is formatting. When the option is off, the formatter can squeeze a multiple-line expression to the Plane style, if it fits within the right margin.

The following example shows how the Preserve Existing Line Breaks option works.

Initial text:

(if (/= s "Function canceled")   (princ (strcat 

	"\nError: "

	s)) ;single semicolon cmt

) 

Formatting result if the option is on (default):

(if (/= s "Function canceled")

  (princ (strcat

		 "\nError: "

		 s

		 )

  )								;single semicolon cmt

)

Formatting result when the option is off:

(if (/= s "Function canceled")

  (princ (strcat "\nError: " s))	;single semicolon cmt

) 

Note that multiple-line princ and strcat expressions are compressed to a single line.
