Wrong comment captures

[GMishx]

Nirjas currently gets confused if the comment is something like /*********/ or /* <comment> */ in C.

For example, following were marked as comments:

1. https://github.com/xdebug/xdebug/blob/192aba841a6332b09b475fa3926a5c5a6edf3071/src/lib/var.c#L177-L203
2. https://github.com/xdebug/xdebug/blob/192aba841a6332b09b475fa3926a5c5a6edf3071/src/lib/var.c#L201-L207 (the comment captured was " ** Data returning functions ")
3. https://github.com/xdebug/xdebug/blob/192aba841a6332b09b475fa3926a5c5a6edf3071/src/lib/var.c#L205-L1018
4. https://github.com/xdebug/xdebug/blob/192aba841a6332b09b475fa3926a5c5a6edf3071/src/lib/var.c#L352-L1054 (captured `" ** XML encoding function ")
5. https://github.com/xdebug/xdebug/blob/192aba841a6332b09b475fa3926a5c5a6edf3071/src/lib/var.c#L365-L1131

Also, http:// is marked as single line comment:

1. https://github.com/xdebug/xdebug/blob/192aba841a6332b09b475fa3926a5c5a6edf3071/src/lib/var.c#L10 (captured "/xdebug.org/license.php")
2. https://github.com/xdebug/xdebug/blob/192aba841a6332b09b475fa3926a5c5a6edf3071/src/lib/var.c#L1158 (captured "/www.php.net/")
