[Bug-readline] unfreed memory allocated within rl_initialize

[Andreas Grapentin]

Hello,

I am currently trying to verify that an application of mine does not
leak memory, and I noticed that the readline library does not free some
allocations below the rl_initialize function.

In numbers, these are approximately 200 blocks, totalling at 150kB. This
creates a lot of noise in my memory profiler, and I find it hard to
verify that no leaks are in my part of the code.
Am I using the library wrong, or is this expected behaviour?

Thanks,
Andreas
