            Bug ID: 107967
           Summary: System path on Unix starting with double-slashes
                    converted to single slash
           Product: LibreOffice
           Version: Inherited From OOo
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: chris.sherlock79 at gmail.com

It appears that in the OSL code that we do some sanity checking for Unix system
paths and convert double slashes (//) to single slash. However, if a system
path starts with a double-slash then starting with double-slashes we are still
converting this to a single slash.

That's unfortunately not valid. POSIX states the following:

"If a pathname begins with two successive <slash> characters, the first
component following the leading <slash> characters may be interpreted in an
implementation-defined manner, although more than two leading <slash>
characters shall be treated as a single <slash> character."

In other words, the following path...

//path/to/file.txt

it becomes:

//path/to/file.txt

However, the following path...

///path/to/file.txt

this becomes:

/path/to/file.txt
