Subject: [PATCH] tests/fmbtest: avoid false-failure due to reliance on
 MB-correct sed

* tests/fmbtest: Several of these tests would mistakenly fail due to
postprocessing with a combination of sed and locale support that failed
to handle some multibyte characters in the cs_CZ.UTF-8 locale.  Instead
of relying on sed's multibyte support or anything locale-related to
perform this simple filtering, just use this: tr -cs '0-9' '[ *]'
Also, rather than exporting LC_ALL, just set it for each command.
Reported by Nelson H. F. Beebe.
