[PATCH] Unified token breaking logic: support for line comments.

[Alexander Kornienko]

Hi klimek, djasper,

Added BreakableLineComment, moved common code from
BreakableBlockComment to newly added BreakableComment. As a side-effect of the
rewrite, found another problem with escaped newlines and had to change
code which removes trailing whitespace from line comments not to break after
this patch.
