[PATCH v2 4/9] diff --color-moved-ws: demonstrate false positives
From: Phillip Wood <hidden>
Date: 2018-11-23 11:17:18
Subsystem:

Linus Torvalds
From: Phillip Wood <redacted>
'diff --color-moved-ws=allow-indentation-change' can highlight lines
that have internal whitespace changes rather than indentation
changes. For example in commit 1a07e59c3e ("Update messages in
preparation for i18n", 2018-07-21) the lines
- die (_("must end with a color"));
+ die(_("must end with a color"));
are highlighted as moved when they should not be. Modify an existing
test to show the problem that will be fixed in the next commit.
