Tab and C-h interacting?

[mlhetland]

Is <Tab> somehow using <C-h>? If I try to map <C-h> to something (specifically with imap), it works, but the tab key starts acting up in julia-vim (but nowhere else). As an example, I'll start out with a .vimrc with just the minimal Vundle setup for including julia-vim, and no other mappings or code.

Then I add the following (before the Vundle block):

imap <C-h> Hello, world!

Starting vim with this .vimrc, if I edit a non-Julia file, pressing <Tab> (in insert mode) will insert a tab, and pressing <C-h> will insert Hello, world!.

If I edit a Julia file, <C-h> also does its job, but pressing <Tab> will now insert:

<91>Hello, world!

where there is a tab character after Hello, world!. If I start the line with, say, \alph and then press tab, I get the completion:

\alpha

I press it again, and get:

α<91>Hello, world!

This time without a tab at the end.

The <91> is a Unicode "PRIVATE USE ONE".

It seems to me that this behavior is a bug, and that it is a bug in julia-vim – but I may very well be mistaken…

Thanks for the detailed report. It was an oversight: <C-H> is the backspace, which is what was being called.
