Support bracket expansion according to Python PEP8

[sebdah]

I would like to be able to <CR> expand according to the following pattern in order to write PEP8 compliant code.

Typing this:

 my_function(|<CR>

to get:

my_function(
    |)

rather than:

my_function(
    |
)

Thanks for an awesome plugin!

[Raimondi]

It looks like you need to use let delimitMate_expand_cr = 0 or au FileType python let b:delimitMate_expand_cr = 0, because the behaviour you describe is the one with <CR> expansion off.

[Raimondi]

Please reopen the issue if needed.

[sebdah]

Thanks for the reply. Unfortunately this does not work. Setting let delimitMate_expand_cr = 0 gets the following behaviour:

my_function(|<CR>)

Results in:

my_function(
|)

While expected would be:

my_function(
    |)

[Raimondi]

For me that results in :

my_function(
        |)

open an empty buffer and :set ft=pyton then paste the output of :DelimitMateTest here.

There is also a basic_vimrc in the repo, copy it and put the the basic setup needed to reproduce your problem there, if you can do it.

Thanks for the advice. I didn't have time today to change the vimrc, but here's the output from the test:

(comment updated since I accidentally did this without having the au FileType python let b:delimitMate_expand_cr = 0 setting in my vimrc)

[Raimondi]

I see you are not using the built-in indent plugin, maybe that has something to do with it. BTW, modify basic_vimrc and run vim with vim -N -u basic_vimrc foo.py

Please, reopen the issue if you still have troubles.
