** matcher

** matcher

[Borsenkow Andrej]

With this style

zstyle ':completion:*' matcher-list '' 'm:{a-z}={A-Z}' '+r:|[._-]=** r:|=**'

the following does not match

bor@itsrm2% gdiff --i-lTAB

but the following does

bor@itsrm2% gdiff --i--lTAB
bor@itsrm2% gdiff --ignore-blank-lines
Completing option
--ignore-blank-lines     -- ignore lines that are all blank
--ignore-matching-lines  -- ignore lines that match regex

Why?

Because that pattern-matching-before-calling-compdescribe has to come in
the loop (otherwise the matchers returned by _next_label won't be used).

And I found a buglet in bin_compadd() where using `--' before the
matches made any -M be ignored.
