lnum.c doesnt handle lines longer than 1024 chars

Also no format specifier is used to tell to the program to scan until the newline character is met.

edit: I've mistaken f/scanf with fgets

The solution which I would like to propose is to read the file content at once with malloc, and split the string into tokens. This way no matter how long a single line could be, it will be numbered properly. I will use this strategy to contribute around 10 programs later on next week.

Shadowing the function read() isn't pretty.
