check-code: build translation table for repquote in global for efficiency Rebuilding translation table (256 size) at each repquote() invocations is redundant. For example, this patch decreases user time of command invocation below from 18.297s to 13.445s (about -27%) on a Linux box. This command is main part of test-check-code.t. hg locate | xargs python contrib/check-code.py --warnings --per-file=0 This patch adds "_repquote" prefix to functions and variables factored out from repquote() to avoid conflict of name in the future.
