[9fans] Acme button 2 argument expansion: feature or bug?

[Paul Lalonde <plalonde@telus.net>]

I've been using gdb a lot with acme lately, and setting breakpoints by 
line number.  I thought I'd do this most easily by doing an Edit =  to 
find the source line then click on the result in the +Error window, and 
middle-click/left-click chord on the convenient "break" I've left lying 
around my debug window's tag line.
But the expansion for the middle button doesn't tack on the : and line 
number.
So I thought I'd just select the whole line and do the chord, but the : 
and line number get chopped off my selection!
Is there a rationalle for trimming my selections when chording 2/1?  
Otherwise I'll fix it and submit a patch.

Less importantly, most of the code I have to deal with is in C++, evil 
as it is, but the expand function doesn't know about ::, which makes 
selecting methods more difficult than it needs to be.  I'm more than 
willing to add that support if someone doesn't convince me I'm wasting 
my time :-)

Thanks,
