It just so happens that substring is the default search mode :-)
Usually, results are filtered to show only "better-than-substring"
matches, but if not such results are found, all results are displayed
(and you can force that with --search (or its new name --showall)).

With upcoming texdoc:

Anyway, I made regex mode issue the following warning:

> Regex mode is deprecated and will likely be removed soon.
> Please protest on the texdoc mailing list if you need this.

If nobody protests for, say 1 month, I'll probably drop it.
