[#148] command being typed as neither green nor red

[danielshahaf]

Related to #148: this patch adds a highlight style for the command word, while it is being typed (similar to path_prefix).

The style used is yellow underline, the same style the now-removed path_approx used.

The intention is to avoid the unknown-token style whilst inputting the command. Future changes may fine tune this further (as discussed in #148), for example, only use the new style when the input-so-far is a prefix of a command or function name.

Perhaps this should use $#LBUFFER (= $CURSOR) instead of $#BUFFER.

Can this use command_prefix or arg0_prefix to be consistent with other in progress styles?

[vegerot]

I still think a command_prefix or arg0_prefix would be very useful to me and others. Is there any progress on allowing this?

[danielshahaf]

Thanks for the ping. Milestoning: small change, but destabilizing, so 0.8.0. (0.7.0 is closed for destabilizing changes.)

Cross-referencing #695.

This is really a sub-issue of #695, so taking this out of the milestone. #695 is still milestoned (not sure whether it'd be fixed before the release, but it's on the shortlist).
