perf: support looking up multiple revisions
The nodemap code has optimisations around the number of lookup we actually made.
As a result, being able to specify multiple revisions to look up is important
when measuring performances. One can now specify full revspecs with the --rev
arguments.
# See http://EditorConfig.org for the specification

[*.py]

trim_trailing_whitespace = true
[*.{c,h}]

indent_style = tab
trim_trailing_whitespace = true
