Seeking during a fade-out unsets the fade, causing the track to then loop indefinitely.

What steps will reproduce the problem?
1. Call gme_seek() to just before a fade-out.
2. Wait until during the fade-out.
3. Call gme_seek() to before the fade-out.
4. Watch as track loops indefinitely.

What is the expected output? What do you see instead?
The expected output is for gme to still fade out at the right time. Instead, 
there's no fade out. I can see this potentially being intended? I worked around 
it in my project by re-setting fades after every seek, but I figured I should 
report this anyway.

What version of the product are you using? On what operating system?
v0.6.0. on Windows, compiled with MSYS/MinGW.

Please provide any additional information below.
The project that uses libgme that I'm working on is a GME-based winamp plugin,
