incompatibility with trim_trailing_white_space_on_save

[akvadrako]

I have trim_trailing_white_space_on_save = true in my user settings. This means that every time autosave triggers, if I had just typed a space, it gets removed.

It would be nice if autosave somehow didn't do that.

Yeah, I can see that might be annoying. Although what we really need is just to not trim the current line; I would like to trim other lines that I am done working on. Otherwise the auto-saved version would be too different from the "ctrl+s" manually saved file. Other editors (e.g. Komodo Edit) has an option to not trim the current line when trimming trailing white spaces.

As a short term solution, you can increase the auto-save delay, but I can see that's not really an optimal solution. A better solution might be to have auto-save manually trim the current view, but exclude the current line. AFAIK, it is not possible to alter the behaviour of Sublime Text when saving, i.e. if you have trim_trailing_white_space_on_save enabled, then sublime text will trim trailing white spaces, just like when you manually save with ctrl+s. And there is nothing we can do from the plugin side to change that. Other than, perhaps, toggling trim_trailing_white_space_on_save off before saving, and on again after saving.

This does seem a bit like another example where it would be nice to customize how the API save command is invoked. We have a similar case where we don't want Sublime Text to hide word completions when saving (PR #27). In other words, it would be nice to be able to invoke save with something like: view.run_command("save", {"trim_trailing_white_spaces": False, "hide_autocomplete_popup": False})) -- where the second argument is a dict to customize the behaviour of the save command, in this case not hiding autocomplete popups and not trimming trailing white spaces.
