[mike-zueff]

Hello @scrooloose,

Within this pull request I propose the fix in order to allow read-only files to be opened as well as regular files.

I would really want this fix to go in asap. Currently NerdTree is not usable for me, as my scm makes all files read-only...

Looking at dfb9111#diff-f094542718c161e8482e397da4e1f499L378 there is no need to introduce exec there.

Instead of

exec 'let line = substitute (line, " \['.g:NERDTreeGlyphReadOnly.'\]", "","")'

just do

let line = substitute (line, ' \['.g:NERDTreeGlyphReadOnly.'\]', "","")

@mike-zueff would you mind updating your PR? Thanks ;)

[scrooloose]

Merged, thanks for the fix!

@scrooloose Maybe I'm missing something but is that exec really necessary there?

[scrooloose]

@mkoskar - good point.
