New command completion: be case insensitive

[kiryph]

My original dictionary completion example for $\right showed also the candidates \Rightarrow and \Rrightarrow which is not the case right now. I can get the uppercase variant when I already use the upper leading R.

IMHO this is helpful to see variants you might be interested in.

Another issue is that I do not see \Rrightarrow even though I added the package amssymb and the file amssymb with the correct entry exists.

\documentclass{article}
\usepackage{amssymb}

\begin{document}
\R
\end{document}

Pressing <Leader>li does not list any packages.

The first part: If \right should include \Rright, then the regex filter can not be anchored. I anchored it after one of your comments, because it seems natural that one starts to type the start of a command. However, I agree that we can make the filter case insensitive.

The second issue is a separate issue. However, I can't reproduce it. That is, it works as expected for me. Note that the list of packages is only parsed when initializing.

Sorry, the second issue was again an outdated neocomplete menu. Pressing ctrl-x ctrl-o revealed all the candidates.

Update
Adding to my vimrc let g:neocomplete#enable_refresh_always=1 (default 0 which means off), updates the menu always (with screen flickering) and I see all possible entries. I am not sure whether I keep this setting due to the flickering.

Ah, yes. Neocomplete does not work perfectly when there are very many completion candidates. The refresh_always option works, as you say, but I keep it off for the same reason you mention.
