This patch adds missing newlines, trims multiple redundant final newlines into a single one, and trims redundant leading newlines. According to POSIX, a line is a sequence of zero or more non-' <newline>' characters plus a terminating '<newline>' character. [1] Files should normally have at least one final newline character. C89 [2] and later standards [3] mention a final newline: "A source file that is not empty shall end in a new-line character, which shall not be immediately preceded by a backslash character." Although it is not mandatory for all files to have a final newline fixed, a more consistent and homogeneous approach brings less of commit differences issues and a better development experience in certain text editors and IDEs.

* @version 1.1
|
|
*
|
|
* Using this class you can iterator over all groups of a ini file.
|
|
*
|
|
* This class uses a 'is-a' relation to KeyFilter in contrast to a 'has-a'
|
|
* relation. Doing so both current() and key() methods must be overwritten.
|
|
* If it would use a 'has-a' relation there would be much more to type...
|
|
* but for puritists that would allow correctness in so far as then no
|
|
* key() would be needed.
