[PATCH 1/3] git-gui: Adapt discovery of oguilib to execdir 'libexec/git-core'

[Steffen Prohaska <prohaska@zib.de>]

The new execdir has is two levels below the root directory, while
the old execdir 'bin' was only one level below.  This commit
adapts the discovery of oguilib that uses relative paths
accordingly.
