[Bug-indent] Bug indent-2.2.9 C++ const method declaration [patch]

[Jim McLaughlin]

Hi,
We ran into the known bug in which a const c++ method signature has the
const tag duplicated by indent-2.2.9.  For example:

// begin file

void foo::fn() const
{
   cout << "Hello, World" << endl;
}

// end file


outputs the following

// begin file

void foo::fn() const const
{
   cout << "Hello, World" << endl;
}

// end file


Looking through the code, we saw that the handle_token_decl function in
indent.c has a special case for ignoring the const in c++ method
signatures. This case skips the tag but does not advance the parse
stream to the next token. The attached patch sets token = token_end at
the end of the case, which resolved the problem. All the regression
tests ran fine.

Hope this helps,

Jim McLaughlin
