simplemerge: avoid quadratic concatenation when building output text...

simplemerge: avoid quadratic concatenation when building output text I haven't checked if the difference is measurable, but the new version is no less readable or idiomatic, so I don't think performance numbers are needed. Differential Revision: https://phab.mercurial-scm.org/D9549

mercurial/thirdparty/cbor/README.rst

This library provides encoding and decoding for the Concise Binary Object Representation (CBOR) (RFC 7049) serialization format.

There exists another Python CBOR implementation (cbor) which is faster on CPython due to its C extensions. On PyPy, cbor2 and cbor are almost identical in performance. The other implementation also lacks documentation and a comprehensive test suite, does not support most standard extension tags and is known to crash (segfault) when passed a cyclic structure (say, a list containing itself).
