[pre-grohtml]: Fix code style nits.
* src/preproc/html/pre-html.cpp (get_line): Boolify: demote return type
from `int` to `bool`, and return Boolean rather than integer literals.
Mark as `static` since this function requires no external linkage.
Reorder equality comparisons to avoid inadvertent lvalue assignment.
Also annotate null pointers with `nullptr` comment to ease any future
transition to C++11, which defines it as a keyword.
