Permission errors are handled in text_load(). To detect these errors,
and other open() errors (opening a directory, for example), check the
return value of text_load().
This fixes a segmentation fault when opening a directory.
Also, opening a file you are not permitted to read, will now give an
error, instead of showing the file as empty.
