From d192fa91f68231152a20ba30549af1333fd33c6c Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 17 Dec 2019 13:16:34 +0100 Subject: [PATCH] mingw: only test index entries for backslashes, not tree entries During a clone of a repository that contained a file with a backslash in its name in the past, as of v2.24.1(2), Git for Windows prints errors like this: error: filename in tree entry contains backslash: '\' While the clone still succeeds, a similar error prevents the equivalent `git fetch` operation, which is inconsistent. Arguably, this is the wrong layer for that error, anyway: As long as the user never checks out the files whose names contain backslashes, there should not be any problem in the first place. So let's instead prevent such files to be added to the index.
