My name is Hoang and I'm involved in correcting Vietnamese translation for Blender. I'm living in London, UK. In the po.vi, I found this text line:
#. :src: bpy.types.MESH_OT_inset.use_edge_rail
msgid "Edge Rail"
This is located in the source file:
and I believe it was committed by you:

code cleanup: split editmesh_tools.c, into inset, bevel (both modal operators) and moved extrude operators into their own file. also move some selection operators from editmesh_tools.c into editmesh_select.c
Could you pls explain what do you mean by the word: "Edge Rail"?
I tested and found that it affects on the cross lines only, as found in the test file attached. Tab into edit mode then perform 'I' (Inset faces). You should be able to select 'Edge Rail' and see the effects.
Does this mean
"Follow the railing edge" (as in the railway line)
"Keep straight with railing edge"
Ps. You can use this file to test it out.
