This commit adds a `NERDTreeCreatePrefix` setting that can be used to
prefix the `:edit` command that is used to create the NERDTree tree
window. Defaults to "silent", meaning that out of the box the window
will be created with "silent edit".
Users may wish to configure this to produce other effects. For example,
`NERDTreeCreatePrefix` can be set to "silent keepalt keepjumps" in order
to make NERDTree create its window with "silent keepalt keepjumps edit".
This can be used to create an effect analogous to the `g:netrw_altfile`
setting in netrw. An example of why you might want to do this is
described here:

I'm not using vim-vinegar myself, but I am using something like it here:
https://github.com/wincent/wincent/blob/3efaa8fa50895/roles/dotfiles/files/.vim/plugin/mappings.vim#L60
And having `NERDTreeCreatePrefix` enables me to map "-" to show the
current file in context, and `^-6` to jump back to it.
Previously maps like T would not restore the cursor position. Not sure
why the code was like this in the first place... hopefully I haven't
just broken a bunch of shit.
Closes#146.
Use +/~ for windows - which seems to not have the arrow chars in its
default font. TBH I don't really understand this.
Inprove the UI indent matching so that it should handle any combo of
open/close symbol lengths e.g. the fancy arrows are 3 bytes each,
whereas +/~ are 1 byte each.
Use the innermost dirs flags only. Previously each dirs flags were
rendered inline i.e.
[x]dir1/[y]dir2/[z]dir3/
This looked bad and broke the UI. Now we only render the flags for dir3
- and render them on the left side of the cascade.
Not sure if this is ultimately the right decision - but will do for now.
Render cascading dirs on one line i.e.
> foo/bar/baz
file1
instead of
> foo
> bar
> baz
> file1
This should be useful things like java projects that have deep dir
structures.
Remove the old UI view (pre the dir arrows) as this simply isnt worth
supporting for a proof of concept. This may get added back - or not.
rename s:format to s:sortKeyFormat - purely for descriptive reasons
rename self.sortKey to self._sortKey - the convention is to use leading
underscores to indicate private vars
On bufleave we save the nerdtree window state. However, sometimes when
bufleave is triggered the tree is no longer open in this tab - e.g. for
secondary trees or mappings that open in another tab. Dont bother saving
screen state in these cases as the code doing the saving assumes the
tree is available in this tab.
Add an API to allow custom "path filter callbacks" to be added.
Previously we allowed one path filtering function to exist called
`NERDTreeCustomIgnoreFilter`. This has been removed and replaced with an
API to allow any number of such functions to exist - via the new
`NERDTreeAddPathFilter()`
