Was writing `size` chars but the `hl` array was allocated as `rsize` chars.
With `'\` or `"...\` as the last characters on the line, `HL_STRING` could be written beyond the allocated size of the `hl` array, causing heap corruption and SEGV.
The test for a keyword would try to read the entire length of each keyword from the line position even if the rest of the line was too short to contain that keyword. A PR was already submitted for this but the author closed it before it could be merged.
