Subject: * Better handling of Windows paths (\php\any_thing or c:\php\any_thing)
X-Git-Tag: php-4.3.0dev-ZendEngine2-Preview1~172
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=59071dc42e9ac38812f331edef3f123b3ba3237e;p=php

* Better handling of Windows paths (\php\any_thing or c:\php\any_thing)
* Remember that inside the archive path are all the time in unix format /php/any_thing
* When necessary, '\' are replaced by '/' and 'c:' are removed
* Synchro with cvs:pear/Archive_Tar/Tar.php version 1.20
