Bug: history-search-backward ignores search text after first space character?

)

 use a lot of git commands and since they are mostly 2-word command names,
matching doesn't find the closest match. For example:

# type in some commands
git checkout -
git status
mvn test
# try to autocomplete based on the history. I want "git checkout -" to
be filled in, but instead "git status" is filled in.
git c<history-search-backward>
git status

Notice the space and c that I typed in are ignored in the autocomplete.

I assume this is some shortcoming of the zsh completion system. Is this
true? Or am I misunderstanding the functionality?

Read the doc:

history-search-backward (ESC-P ESC-p) (unbound) (unbound)
     Search backward in the history for a line beginning with the first
     word in the buffer.

Note that only the first word is used for that widget.

History search has nothing to do with completion (though completion might
search the history), so yes, you're misunderstanding.

What you want in the example shown is history-beginning-search-backward, 
which is not bound by default.  Add

zle -A history-beginning-search-backward history-search-backward
zle -A history-beginning-search-forward history-search-forward

to your .zshrc (there are other ways to accomplish the same thing if
you still want to be able to use the original history-search-backward
and -forward widgets).
