Removed division from get_stdin, and made it fail properly on failed allocation
Fixed the retard brain #include syntax/c.h shit (god I hope I didn't break highlightlighting I'm not - I checked and it outputs the same under the last commit, it's probably fine anon'll fix it what a cuck)
Much better input handling, properly using perror and handling multible files even under a noexist condition, probably fixed a seggy on noexist condition
