test-dirstate: fix detection of Rust environment variable...
test-dirstate: fix detection of Rust environment variable The Rust path never actually worked. This change also improves clarity of the comment. The next change will ensure we print something when this check fails. Differential Revision: https://phab.mercurial-scm.org/D12601

Issue1790: dirstate entry locked into unset if file mtime is set into
the future
Prepare test repo:
$ hg init u
$ cd u
$ echo a > a
$ hg add
adding a
$ hg ci -m1
Set mtime of a into the future:
$ touch -t 203101011200 a
Status must not set a's entry to unset (issue1790):
$ hg status
$ hg debugstate
n 644 2 2031-01-01 12:00:00 a
Test modulo storage/comparison of absurd dates:
#if no-aix
$ touch -t 195001011200 a
$ hg st
$ hg debugstate
n 644 2 2018-01-19 15:14:08 a
