complete_files error

[ivanbrennan]

The following steps lead to an error:

• invoke Grepper command
• enter an alphanumeric character
• hit Tab
• hit Escape

:Grepper<CR>
a<Tab><Esc>

Expected result: cleanly exit ex mode

Actual result: Error

@ivanbrennan do you have more information on your setup? vim and vim-grepper version, vim-grepper configuration and installed plugins?

I don't see it happening on stock configuration.
