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.
