Subject: escape brackets in path.pattern

path.pattern() escapes the lua pattern magic characters except '[' and
']', so a filename containing brackets is treated as a character class.
For example, os.files("a[1]*.lua") matches "a1.lua" instead of
"a[1].lua", and remove_files("a[1].lua") would remove "a1.lua"
instead of "a[1].lua".

Escape '[' and ']' like the other magic characters so bracket
characters in file names are matched literally.
