[Yum-devel] [PATCH 1/2] Remove erase transactions on reinstall, fixes BZ 512393.

[James Antill]

 The main problem here is that yum doesn't let a user install blah-1, if
blah-1 is already installed ... so we require a remove transaction, and
then an install transaction of the same thing.
 However _rpm_ only wants to see the install transaction, and gets upset
with the remove transaction as well (it has an implicit remove as part
of the install, and so tries to remove twice).

 So this fix just removes the "remove transaction" when we add the
reinstall "install transaction".
