Hi,
Here is an update.

- getsign('lnum')
returns a list of all placed sign ids in line lnum in the
current buffer
-getsign()
returns a list of all placed sign ids in the current buffer
Also this patch compiles for non-sign builds (which the previous patch
did not because of a missing #ifdef).
regards,
Christian
