rev-branch-cache: fix message about overwritten data
If there is data at the end we ignore, we should not count them as overwritten.
This reveal that we something don't overwrite anything, this will be taken car
of in the next changeset.

perf extension - helper extension to measure performance
Configurations
==============
"perf"
------
"all-timing"
When set, additional statistics will be reported for each benchmark: best,
worst, median average. If not set only the best timing is reported
(default: off).
"presleep"
number of second to wait before any group of runs (default: 1)
"pre-run"
number of run to perform before starting measurement.
"profile-benchmark"
Enable profiling for the benchmarked section. (by default, the first
iteration is benchmarked)
"profiled-runs"
list of iteration to profile (starting from 0)
"run-limits"
Control the number of runs each benchmark will perform. The option value
should be a list of '<time>-<numberofrun>' pairs. After each run the
conditions are considered in order with the following logic:
If benchmark has been running for <time> seconds, and we have performed
<numberofrun> iterations, stop the benchmark,
The default value is: '3.0-100, 10.0-3'
"stub"
When set, benchmarks will only be run once, useful for testing (default:
off)
