In zshcompsys(1), in the description of the special context

   zstyle ':completion:*:*:-redirect-,2>,*:*' file-patterns '*.log'
 is another way  to make completion after `2> <TAB>' complete files
 matching `*.log'.

This works fine. But if I try the following to restrict this
to a specific command, say make,

   zstyle ':completion:*:*:-redirect-,2>,make:*' file-patterns '*.log'

it does not work; 'make 2> <TAB>' offers all the files.
'make 2> ^Xh' shows:

tags in context :completion::complete:-redirect-,2>,/usr/bin/make::
    globbed-files  (_files _redirect)

so the context includes not 'make' but '/usr/bin/make'.
I think the problem is in the last line of _redirect:

_dispatch -redirect-,{${compstate[redirect]},-default-},${^strs}

The 'context' argument to _dispatch is missing, so the 1st
word of the results of the brace expansion (with RC_EXPAND_PARAM)
is used as the 'context'.

_value has a similar use of _dispatch with explicit 'context' arg.
