i18n: fix "% inside _()" problems
Before this patch, "contrib/check-code.py" can't detect these
problems, because the regexp pattern to detect "% inside _()" doesn't
suppose the case that format string consists of multiple string
components concatenated implicitly or explicitly,
This patch does below for that regexp pattern to detect "% inside _()"
problems in such case.
- put "+" into separator part ("[ \t\n]") for explicit concatenation
("...." + "...." style)
- enclose "component and separator" part by "(?:....)+" for
concatenation itself ("...." "...." or "...." + "....")
i18n: fix "% inside _()" problems
Before this patch, "contrib/check-code.py" can't detect these
problems, because the regexp pattern to detect "% inside _()" doesn't
suppose the case that the format string and "%" aren't placed in the
same line.
This patch replaces "\s" in that regexp pattern with "[ \t\n]" to
detect "% inside _()" problems in such case.
"[\s\n]" can't be used in this purpose, because "\s" is automatically
replaced with "[ \t]" by "_preparepats()" and "\s" in "[]" causes
nested "[]" unexpectedly.
