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.

These functions check whether a character or string
|
|
falls into a certain character class according to the i
|
|
current locale.

<para>
|

When called with an integer argument these functions

behave exactly like their C counterparts.

</para>

<para>
|
|
When called with a string argument they will check
|
|
every character in the string and will only return
|
|
true if every character in the string matches the
|
|
requested criteria.

</para>

Passing anything else but a string or integer will
