[9fans] plan9 function names

["Michael Teichgräber" <mt@wmipf.in-berlin.de>]

Hi,

is there a reason why underscores are avoided in most function and
variable names on Plan 9? I have used this style for a while now, and
it seems to me that it increases the over-all code readability, as
names or function calls can be more easily recognized. Without
underscores one has to look for shorter or more to the point
function/variable names. But sometimes an ambiguity might remain, since
words are not separated from each other.

Or, is it just a habit without a specific reason?
