largefiles: fix trailing spaces in test-largefiles.t With the default branch this will cause warnings from check-code.

test-hybridencode: add a case for direncode

store: optimize fncache._write by direncoding the contents in one go For a netbeans clone on Windows 7 x64: Before: $ hg perffncachewrite ! wall 0.210000 comb 0.218401 user 0.202801 sys 0.015600 (best of 47) After: $ hg perffncachewrite ! wall 0.104000 comb 0.109201 user 0.078000 sys 0.031200 (best of 95)

store: move encode lambda logic into fncachestore and define two named functions at module scope. This again also speeds up perffncacheencode a little bit.
