check-code: detect "% inside _()" when there are leading whitespaces Before this patch, "contrib/check-code.py" can't detect "% inside _()" correctly, when there are leading whitespaces before the format string, like below: _( "format string %s" % v) This patch adds regexp pattern "[ \t\n]*" before the pattern matching against the format string. "[\s\n]" can't be used in this purpose, because "\s" is automatically replaced with "[ \t]" by "_preparepats()" and "\s" in "[]" causes nested "[]" unexpectedly.
