Accept patches with a/ and b/ prefix #9

Closed bradleyfalzon closed 8 years ago

bradleyfalzon commented 8 years ago

We need to accept patches which have the a/ and b/ prefixes, eg:

index 0000000..2293375
--- /dev/null
+++ b/main.go

We were stripping them out before, because we could, but if you're providing a patch, you may not be able to strip them out yourself.

This should be straight forward, something like:

diff --git a/revgrep.go b/revgrep.go
index 19e111f..61e3fe3 100644
--- a/revgrep.go
+++ b/revgrep.go
