Trim unneeded leading components and trailing zeros.
Move the formating code in a separate function.
Use the function also to format the default value, it was currently
printed as plain integer, inconsistent to the way it is parsed.

Example:
% ./ffmpeg -h encoder=gif
[...]
GIF encoder AVOptions:
  -gifflags          <flags>      E..V.... set GIF flags (default offsetting+transdiff)
     offsetting                   E..V.... enable picture offsetting
     transdiff                    E..V.... enable transparency detection between frames

Example:

% ./ffmpeg -h encoder=aac
  -aac_coder         <int>        E...A... Coding algorithm (from -1 to 3) (default twoloop)
     faac                         E...A... FAAC-inspired method
     anmr                         E...A... ANMR method
     twoloop                      E...A... Two loop searching method
     fast                         E...A... Constant quantizer
