[evolution-patches] e-plugin.c: Fix for compiler warning (RH bug #162136)

[David Malcolm <dmalcolm redhat com>]

Attached patch fixes a compiler warning under GCC4:

e-plugin.c:93: warning: comparisons like X<=Y<=Z do not have their
mathematical meaning

(as noted in
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=162136 )

Have I correctly understood the intent of this code?  OK to commit?

Dave
