Fix lexing of empty comments continuing till next line
Empty comments (comments without any characters including spaces after
//) had a bug during lexing. The lexer did not recheck the current
character after skipping / characters. When there was no character after
//, the lexer skipped the next newline character. This caused lexer to
count the next line as a part of the comment to. This commit fixes this
bug by rechecking current character after skipping two / characters.
