From 63ec5e1fecc14b0dd5452f0a2b80641600b03437 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 28 Sep 2015 18:12:18 +0200 Subject: [PATCH] setup: fix "inside work tree" detection on case-insensitive filesystems Git has a config variable to indicate that it is operating on a file system that is case-insensitive: core.ignoreCase. But the `dir_inside_of()` function did not respect that. As a result, if Git's idea of the current working directory disagreed in its upper/lower case with the `GIT_WORK_TREE` variable (e.g. `C:\test` vs `c:\test`) the user would be greeted by the error message fatal: git-am cannot be used without a working tree. when trying to run a rebase. This fixes https://github.com/git-for-windows/git/issues/402 (reported by Daniel Harding).
