Comments aren't parsed correctly

[unmanned-player]

When a comment appears as part of list it fails to parse correctly. See an example below:

targets = {
    "Life", # Comment
    "Universe",
    "Everything"
}

In this list, a comment appears along with one of the list items and fails with the error:

simple.conf:1: unexpected token 'Comment'

The lexer suggests,

 /*
  * handle one-line comments
  *
  * Note: Comments with lots of leading #### or //// are fully
  *       consumed and are not included in CFGT_COMMENT yylval
  */
"#"{1,}.*   return qstr(cfg, '#', CFGT_COMMENT);
"/"{2,}.*   return qstr(cfg, '/', CFGT_COMMENT);

So I added extra '#' to see if this goes away. But it didn't.

Sometimes in our usage, we do comment out a few configuration items or leave a comment next items. The new parser in 3.3 (master) seems to be also collecting comments for some reason.

Note, we were using libConfuse version 3.0 and were planning to move to 3.3 owing to some memory leak fixes. But there seems to be some feature about CFGF_COMMENTS for which I can't seem to find proper documentation on to understand the rationale behind it.

What is the right way to comment out or put comments inside of lists?

This is not good. Definite bug in the lexer, because just about any type of C/C++/UNIX style comment should work ...

Hi, to add to this, comments of the kind:

foo /* comment */ = bar

also don't work. In fact, it looks like the parser believes that */ must terminate the line (if my understanding of this part is correct: https://github.com/libconfuse/libconfuse/blob/master/src/lexer.l#L419
