[PATCH 1/2] Only match complete words in org-export-add-options-to-plist

[Lawrence Mitchell <wence@gmx.li>]

* org-exp.el (org-export-add-options-to-plist): Require match to start
at a word-boundary.

Previously, if an option was the suffix of another option (such as TeX
and LaTeX) the setting for the former would propagator to the latter.
This seems like an unintended consequence of a lax regexp in
org-export-add-options-to-plist.  This patch allows options to share a
suffix with another option by requiring that the match against an
option starts at a word-boundary.
