ui: remove unreachable branches and function calls from write() (issue6059)...

ui: remove unreachable branches and function calls from write() (issue6059) This is at least faster than ui.write() of 4.8.2. $ HGRCPATH=/dev/null hg files -R mozilla-central --time >/dev/null 4.8.2: time: real 2.340 secs (user 2.310+0.000 sys 0.020+0.000) 4.9rc0: time: real 2.580 secs (user 2.550+0.000 sys 0.020+0.000) this: time: real 2.230 secs (user 2.210+0.000 sys 0.020+0.000) Maybe the formatter should own a resolved write() function because it will just call dest.write(msg) most of the time, but that would be too much for stable.
