--text follows this line--
================================================================
Dear Bug Team!

I want to search for the next beginning-of-line or the next space.

When I execute:

     M-: (re-search-forward "\\(?: \\|^\\)")

it recognizes correctly every space and every bol.

But, when I execute:

     M-: (re-search-forward "\\(?:^\\| \\)")

it matches only white spaces, but no beginning of line.

Am I doing something wrong or is it a bug?
