Subject: [PATCH] Shorten long function names in the assembly view.

This is an experimental attempt to prevent functions with long call
signatures from wrapping the Assembly view.  It's thwarted by the
disassembly also including long call signatures in branch targets.

I briefly considered hacking the disassembler output, but the embedded
syntax highlighting makes that more difficult than I wanted to tackle.
Guess I'll just need to refactor the code I work on to pass structures
around instead. :)
