As you may know, if the layout (*.lay) file has other than "\r\n" line endings, they maybe converted to "\r\n", if open (and close or switch to a different file, if "Save file on TheIde window deactivation" is not enabled for Editor settings) mentioned file in TheIDE's layout designer (for example, at 13628 revision). As a consequence, this may affect creation of patches for layout file(s), which may include changes for line endings, among other things. There was a need to convert affected layout file(s) to previous line endings state to fix this.

Some examples of LF ("\n") layout files:
uppsrc/CodeEditor/CodeEditor.lay
uppsrc/CtrlLib/Ctrl.lay
uppsrc/IconDes/IconDes.lay
uppsrc/ide/ide.lay
uppsrc/ide/LayDes/LayDes.lay

Some examples of CRLF ("\r\n") layout files:
uppsrc/Docking/Docking.lay
uppsrc/ide/MacroManager/MacroManager.lay
uppsrc/ScatterCtrl/ScatterCtrl.lay
uppsrc/urepo/urepo.lay
uppsrc/urepo/usvn.lay

I propose to detect known line endings for TheIDE's layout designer, which are used to save the layout to a file.
