lyx_mirror/src/TexRow.h
Jürgen Spitzmüller 879272068b Patch by John McCabe-Dansted to fix bug #6502:
Wrong line count with parent math macros:

* TeXRow.{cpp,h}:
	- new helper function to insert multiple newline at once.

* mathed/MacroTable.{cpp,h}:
* mathed/MacroTemplate.{cpp,h}:
	- make write() an int, returning number of newlines

* Buffer.cpp (writeLaTeXSource):
	- update texrow's newline on parent macro output.
