formulas in [exit] can lead to extreme WML-bloat of savefiles

[GoogleCodeExporter]

formulas can be used effectively in exits, but instead of the formula logic
being carried over into the save file, it is expanded into a separate exit
per hex.

less extreme example:
[exit]
formula="x = 70 or y = 70"
xdst="xyz"
ydst="xyz"
[/exit]
This will fill up the x=70 and y=70 rows with exits, which on a 100 x 100
map is 1000 lines of WML code.

much, much more extreme example (and this is what I've done intuitively,
first):
[exit]
formula="x > 70 or y > 70"
xdst="xyz"
ydst="xyz"
[/exit]
This leads to 5100 lines of WML code if exits are not duplicated (which
they might be?)

It would be much more preferable to keep the formula logic in the save file.
