Martin, I updated the insert test using your last changes, the diff file 
is attached.

I found minor problem in 21.strings.cpp: the enum element sig_void has
value 1, and this value is used as index accessing the signatures array.

I added dummy empty string to the begin of the signatures array to make
indexes valid. The file with differences to 21.strings.cpp is attached.

Here is the change log:
2006-04-24  Anton Pevtsov <antonp@moscow.vdiweb.com>

    * 21.strings.cpp (setvars): Added empty string to signatures
    array to shift elements on 1 position, added formatting
    for insert overloads.


Thanks,
Anton Pevtsov

Anton, this implements some of the features we discussed. In the process
of consolidating code from the individual tests into the 21.strings.cpp
driver file I inadvertently removed some of the command line option
handling. I'll put it back tomorrow. I also plan on moving some
additional code from the tests into the driver and streamlining them
even further.

Let me know how this looks to you and if you have any suggestions for
changes and/or improvements.

Martin
