I am using following vim plugins vinegar and unimpaired.
When I enter a netrw directory listing with -, the mappings of unimpaired starting with c (e.g. toggle line numbers with con) do not work because netrw has mapped the single letter c (:h netrw-c).
I'd like to patch vinegar to add an unmapping for the c mapping of netrw.
For completeness I give here the mapping of c as done in $VIMRUNTIME/autoload/netrw.vim:
nnoremap <buffer> <silent> <nowait> c :<c-u>call <SID>NetrwLcd(b:netrw_curdir)<cr>
I have tried to add in plugin/vinegar.vim to the function! s:setup_vinegar() abort following line
nunmap c
However, this does not work. This might be an issue of the load or evaluation order of vinegar w.r.t. netrw.
UPDATE Sept 2018
Netrw v162 has changed the mapping to netrw-cd and therefore I do not need this anymore.
