Description:
------------
When I send an exception from a stream wrapper method, the call fails with a generic warning message from PHP, but the message I sent with my exception is not displayed.

It would be a useful enhancement to add it to the error string.

(Tested in 5.1.2, should be the same in 5.1.4)



Reproduce code:
---------------
Example of an invalid URL :

include('phk://mnt1/toto');



Expected result:
----------------
If the exception->message was also displayed, it would give something like :

PHP Warning: include(phk://mnt1/toto): failed to open stream: Error opening PHK subfile - phk://mnt1/toto: Invalid URL - mnt1: Unknown PHK mount point - "PHK_Stream::stream_open" call failed in ... on line 6



Actual result:
--------------
PHP Warning:  include(phk://mnt1/toto): failed to open stream: "PHK_Stream::stream_open" call failed in ... on line 6

I have no way to tell the user why his URL failed. And, as STREAM_REPORT_ERRORS is unset, I am not allowed to raise any error from my code.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Sorry, I had a 'catch' part in my code and the exception was trapped before being sent to the calling code.

I still would have ideas for ways to catch exceptions in the stream wrapper code but I need to think more about it before submitting a new enhancement suggestion (for PHP 6). So I prefer to close this case.
