SuperTab Compatibility is Broken

[dhazel]

Vim 7.3.547 (Ubuntu 13.04) Bare config with pathogen loading three plugins:

1. UltiSnips (MarcWeber fork) (https://github.com/MarcWeber/UltiSnips)
2. vim-snippets (https://github.com/honza/vim-snippets)
3. SuperTab (https://github.com/ervandew/supertab)

When either UltiSnips or SuperTab are loaded on their own, they work properly; but when loaded together, I've noticed the following problems:

1. With cursor at the start of an empty line, when the <tab> key is pressed, nothing happens
2. With the cursor preceded by whitespace, when <tab> is pressed, the full snippet list pops up. This is the functionality by default bound to the <C-tab> key combo in Ultisnips.
3. I could not find a case where UltiSnips handed off completion to SuperTab.

Testing all the above cases against the SirVer version of UltiSnips yielded the expected functionality, so this appears isolated to the MarcWeber fork.

Right. Holger Rapp is working on an official new version integrating most of my changes. So before that event (his new release) which might make this branch obsolete it doesn't make sense to me to work on such bug reports at the moment.
