tribby 05d82736bc Changes for gsh version 2.0d10: 
Add check for buffer overflow when globbing, expanding variables, or
inserting aliases (PR#110).  Increase buffer size from 1024 to 4096.

Increase buffer for reading commands from 256 to 1024 bytes in order
to match the maximum length used when reading.
