keyword: enforce subn method via boolean switch

There are only 2 patterns to choose, and so far only 1 case
where kwtemplater.re_kw.subn is applied on data read from
the working directory: when recording added files.

With this change the code reflects more closely the boolean
character of the switch and underlines the special case.
