Using tshark with -z follow,tcp,ascii,<stream number> stops if there is a
missing or broken file in the stream.

For example, if I have a stream containing 12000 bytes with package numbers
reaching up to 4000 if number 300 is filed as missing or broken in wireshark,
the follow option will stop displaying ascii output right after package 299 and
skip all other packages. 

Further testing showed me that this problem also appears in wireshark, when I
use "follow tcp stream" and is the same for Linux and Windows. I tested this
with the last 5 Stables of Wireshark and the current Development Version (in
which -z follow is not working at all, but that is a different problem).

Please help me fix this, for I need this working VERY badly. 

In the meantime a workaround would be appreciated.
