To the best of my understanding, a line can be:

[section]
^\s*\[[a-zA-Z0-9_-]\]\s*

variable=vale
\s*[a-zA-Z0-9_-]+\s*=\s*not_sure

directive=>value
\s*[a-zA-Z0-9_-]+\s*=>\s*not_sure

#specials
\s*#.*

A parser should still be able to tell that:

  this comment line is missing a ';' in the beginnin

is nither of those.
