Silly me. An event handler is a command substitution, so that will always
evaulate to true.
Ok, new approach. Lets' define a cd function. The trouble here is that a
cd wrapper function is already defined, doing things with the directory
history. So we redefine it as __cd_wrapper. Something like this:
eval (functions cd|sed -e 's/function cd/function __cd_wrapper/')\n
function cd
__cd_wrapper $argv
if status --is-command-substitution
return
end
blah blah blah
end
A bit of a hack, but it could be worse.
