From: Andreas Gruenbacher <agruen@suse.de>
Subject: Patch fails to apply hunks with asymmetric context correctly
Patch assumes that hunks with fewer context lines at the top than at the bottom
can only match at the beginning of the file, and hunks with fewer lines at the
bottom can only match at the end. The result is that patches with such hunks
will only apply with fuzz N if the prefix context is N lines longer or shorter
than the suffix context. This makes no sense; hunks with asymmetric context
are perfectly valid.

+ * patch.c (locate_hunk): Hunks that have fewer or more lines of
+ context at the beginning than at the end can match anywhere; the
+ assumption that this can only occur at the beginning or end of the
+ file is wrong.
