The output for nested italic and bold is incorrect. #113

Hi, it seems the output for ***text*** or ___text___ is incorrect. The correct output should be either <em><strong>text</strong></em> or <strong><em>text</em></strong>. Currently, it is <strong><em>text<strong><em></em></strong></em></strong>.

@NguyenHoangHieu22GIT2 Actually, it's impressive considering its tiny source size, but as it consists solely of a single regular expression, fixing any issues is almost impossible.

@0smr AFAIK any lexer can be rewritten into regular expression, if it operates on a language with regular grammar. I believe, fixing issues is hard due to parser being embedded into the lexing process - it basically does everything in a single run.

@AlexanderFarkas I understand that. I just opened the issue so that the maintainer would be aware of it, and any other developer who sees this. However, I didn't wait for any fixes since I was sure that this wouldn't get fixed in the near future.
