Subject: [PATCH] Fix error in setting up xterm-color in eshell
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Apparently when the ‘oni-eshell’ library gets loaded neither
‘eshell-preoutput-filter-functions’ nor ‘eshell-output-filter-functions’ are
ready to be used, even though they are defined in the ‘esh-mode’ libary, which
is loaded at this point in time.
