Subject: 	* src/Spacing.cpp (writeBeginEnv, writeEndEnv): add a bool parameter
X-Git-Tag: 1.6.10~6615
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=3d8828fa1420ca155df167dd9b61d9fe3aabcd37;p=features.git

	* src/Spacing.cpp (writeBeginEnv, writeEndEnv): add a bool parameter
	directing to use memoir's capitalized latex macros.
	* src/LaTeXFeatures.cpp (getPackages): act on feature "SetSpace".
	* src/output_latex.cpp (TeXOnePar): ditto

	* lib/layouts/memoir.layout: provide feature SetSpace, indicating that
	memoir provides the setspace functionality, but with a different syntax.
