bug#8258: INFOPATH bug on Windows

[Ralph Schleicher]

Hi,

on Windows, Emacs 23.3 fails to parse INFOPATH due to a hard-coded
colon as path separator.  Below is a patch together with a change
log entry.


2011-03-11  Ralph Schleicher  <rs@ralph-schleicher.de>

        * info.el (info-initialize): Replace all uses of `:' with
        path-separator for compatibility with non-Unix systems.
        Cache quoting of path-separator.
