* bufferview_funcs.[Ch]: split changeDepthAllowed from changeDepth
|
||||
* lyxtext.h: ditto
|
||||
* text2.C: same thing + updateCounters fix + redoCursor also adjusts
|
||||
selection cursors
|
||||
* lyxfunc.C: adjust
|
||||
* text3.C: adjust + re-allow multi par depth changes
|
||||
* textcursor.C: simplify a bit
