Control-M (^M) error while opening vim over cygwin

[anoopelias]

Hi, I am trying to load ctrlp over cygwin,

I downloaded the bundle, updated the .vimrc and then open vim, I get the following error,

$ vim
Error detected while processing /home/Anoop.Elias/.vim/bundle/ctrlp.vim/plugin/ctrlp.vim:
line    7:
E492: Not an editor command: ^M
line    8:
E15: Invalid expression: ( exists('g:loaded_ctrlp') && g:loaded_ctrlp ) || v:version < 700 || &cp^M
line   15:
E475: Invalid argument: ^M g:ctrlp_allmixes, g:ctrlp_buftags, g:ctrlp_ext_vars, g:ctrlp_builtins]^M = [[], [], [], [], {}, {}, [], 2]^M
line   69:
E171: Missing :endif
Press ENTER or type command to continue

Needless to say CtrlP doesn't work once vim is opened.

It is not ctrlp problem. You must convert files line format.

Tried this,

$ dos2unix .vim/bundle/ctrlp.vim/plugin/ctrlp.vim
dos2unix: converting file .vim/bundle/ctrlp.vim/plugin/ctrlp.vim to Unix format...

Got something like the below, (The error goes on for about 100-200 lines, I pasted only the last part. But it is similar)

E492: Not an editor command: ^M
line  114:
E488: Trailing characters
line  119:

Is there anything else, I can try?

Further,

I tried to convert the file back using unix2dos command and the original error comes back,

$ unix2dos ctrlp.vim
unix2dos: converting file ctrlp.vim to DOS format...

I had exactly the same problem, but on vanilla Ubuntu 16.04. My solution was to disable git automatic end line conversion with git config --global core.autocrlf false before running git clone. I am not sure where the problem lays, but can imagine its both in non-consistency in ctrlP package and git going stupid with some edge cases.
