(svn r4586) - Codechange: Recursive commands that rely on _error_message to handle success/failure can fail if a recursive call fails but doesn't set the error message, thus resulting in an old, possibly erroneous being used (see FS#130 prior to r4585). Now properly reset the global variable _error_message in these cases.

(svn r4572) Remove vehicle_leave_tile_proc
...
There's exactly one implemented function (unbarring a level crossing) and one place where it can be triggered (a train leaves a level crossing)
It's a bit overkill, so just handle this one case where it can happen

(svn r3992) -Fix: Rewrote the code to determine whether a rail-tile can be terraformed.
...
Fixes a bug where you could terraform a tunnel (fixed by r3228, but reverted that one)
Fixes a bug introduced by r3228 which allowed steep rail tiles resulting in ... unwanted effects such as display artifacts.
That means the terraform feature should not work as intended; it also uses _valid_tileh_slopes to determine valid configurations instead of hand-brewn stuff.
TODO: _terraform_err_tile and similar TileIndices should have INVALID_TILE as "unused", not 0. (0 is a valid tile).
