Subject: t7810: turn MB_REGEX check into a lazy prereq
X-Git-Tag: v2.55.0-rc1~8^2~3
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=b1688db759de18a8403945090688b8cc25ba26dd;p=thirdparty%2Fgit.git

t7810: turn MB_REGEX check into a lazy prereq

In t7810 we verify whether the system has proper multibyte locale
support by executing `test-tool regex` with a unicode character. When
this check fails though we'll output an error that breaks the TAP
format.

Fix this issue by turning the logic into a lazy prerequisite.
