Subject: untracked-cache: test untracked-cache-bypassing behavior with -uall
X-Git-Tag: v2.37.0-rc0~102^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a0231869a6d656f1cc9402084898666308d364ef;p=thirdparty%2Fgit.git

untracked-cache: test untracked-cache-bypassing behavior with -uall

Untracked cache was originally designed to only work with
'--untracked-files=normal', and it gets ignored when
'--untracked-files=all' is specified instead.

Add explicit tests for this known as-designed behavior.
