Or I could say RTFM :)

     [NEW] It's possible to provide one or more regexp  
transformations to be applied
     to the symbols extracted via the showInSymbolList bundle  
preference item. This is
     done as a scope specific preference (symbolTransformation) and  
the format of the
     value is: “s/«regexp»/«format»/«options»” optionally followed by  
“;” and more
     regexp transformations. The format string is as in other places  
(see Help ->
     Regular Expressions) so there is support for conditional  
insertions, case folding
     and similar. For a simple example, see e.g. the Python or Ruby  
bundle (Symbol
     List preferences), for a slightly more advanced example, see the  
Objective-C
     bundle.

So that'd be:

     symbolTransformation = 's/\s+/ /g';

With scope set to the thing for which you want the white space  
collapsed. You could also do:

     symbolTransformation = 's/\s+/ /g; s/^(.{30}).+$/$1…/';

Then it collapses white space and chops of anything after the 30th  
character and add ellipsis :)

Be aware that if this is Python methods, a symbol transformation is  
already setup for the scope (so edit that, or better, include what it  
does in yours, and give yours a more exact scope to make it win).

However, I'll add white space collapsing as the default, since it  
makes sense.

Well, it could be done, but requires some work.

You'll have to do a command that does figure out the indent -- see  
e.g. the Markdown bundle which has a command which inserts as many  
='s as the line above, you'd use a similar technique -- then you'd  
have to put this on return but limit the scope to something like  
declaration.parameter.

So it's not a simple preference you can tweak.
