error in 19.3.1

error in 19.3.1

[Roman Neuhauser]

This is near the end of 19.3.1:

For example:

zstyle -e ':completion:*' completer '
    if [[ $words[1] = cvs ]]; then
      reply=(_complete)
    else
      reply=(_complete _approximate)
    fi'

uses the value `_complete' for the completer style in most contexts, but
the value `_complete _approximate' when the first word on the command
line is `cvs'.

You mean the code should be the other way round?

    Aha, sorry.

    Only if the behavior described in the text actually makes sense,
    that is, is this setting useful? Not if the _approximate completer
    bypasses the smarts that make _cvs offer only unversioned files to
    cvs add, only versioned (or scheduled for addition) files to cvs ci,
    etc.
    
    I don't actually know what will _cvs do with this completer
    (svn everywhere I look), I'm just saying this should be considered.

Here's an example I actually use, plus another comment.
