Subject: [PATCH] recursive-merge: Don't print a stack trace when read-tree fails.
X-Git-Tag: v0.99.8~57
X-Git-Url: https://git.octo.it/?p=git.git;a=commitdiff_plain;h=0bed18998ae6c0cec1485e6295be16a4fcebc7a7

[PATCH] recursive-merge: Don't print a stack trace when read-tree fails.

If the working tree is dirty read-tree will fail, and we don't want an
ugly stack trace in that case. Also make sure we don't print stack
traces when we use 'die'.
