Handle deleted directories

[diversys]

If folder containing a file was deleted and recreated in the background (as it often happens with haikuporter -c) Pe fails to save currently opened file. To reproduce:

echo text > folder/file.c
lpe folder/file.c &
rm -rf folder ; mkdir folder

Extremely annoying :/

So what "should" it do? Recreate the missing folder and then try to save there, or switch to "Save As..." mode when an attempt to save is made of an open file but it's directory is now missing? I would assume we've want the second option.

The second option should be fine

Should be fixed now, merged #36, please test.

Seems to work.

Now that I used this feature I would prefer Pe to recreate the missing folder and then try to save there.

[scottmc]

so then the test case becomes:

echo text > folder/file.c
lpe folder/file.c &
rm -rf folder
then try to save file in Pe

I think it's safer to go to a "Save As..." condition, since there may be reasons why a folder disappeared while the file was open in Pe. Blindly recreating that folder could lead to other unforeseen issues. Opening up the "Save As..." view gives the user a chance to figure out how to solve the issue. Perhaps it was on a disk that has now been ejected.
