title: How can I (from a script) add something to the zsh command history?
body: <p>I'd like to be able to look through my command history and know the context from which I issued various commands--in other words, "what directory was I in?"  There are various ways I could achieve this, but all of them (that I can think of) would require manipulating the zsh history to add (for instance) a commented line with the result of $(pwd).  (I could create functions named cd &amp; pushd &amp; popd etc, or I could use zsh's preexec() function and maybe its periodic() function to add the comment line at most every X seconds, just before I issue a command, or perhaps there's some other way.)</p>
  
  <p>The problem is, I don't want to directly manipulate the history file and bypass the shell's history mechanism, but I can't figure out a way (with the fc command, for instance) to add something to the history without actually typing it on the command line.  How could I do this?</p>
