Patch-ID: readline70-001

Bug-Reported-by: Sean Zha <freeman_cha@hotmail.com>

|
Bug-Description:
|
|
|
|
Readline-7.0 changed the way the history list is initially allocated to reduce
|
|
the number of reallocations and copies. Users who set the readline
|
|
history-size variable to a very large number to essentially unlimit the size
|
|
of the history list will get memory allocation errors
|
|
|
|
Patch (apply with `patch -p0'):
