patch: handle 0 context lines (diff.unified=0) when parsing patches
Previously, if there were no context lines, we would just keep updating the
ranges and the hunk, but not actually storing the hunk (just overwriting it each
time). Thus a diff like this:
$ hg diff --config diff.unified=0
diff --git a/bar b/bar
--- a/bar
+++ b/bar
@@ -1,0 +2,1 @@ 1
+change1
@@ -3,0 +5,1 @@ 3
+change2
would come out of the parser like this (change1 is lost):
bar:
@@ -3,0 +5,1 @@ 3
+change2
This had some really weird side effects for things like commit --interactive,
split, etc.

Test the "--base" flag of the rebase command.
