Mercurial Push from IntelliJ

I've been using IntelliJ on a recent project because of its Groovy and Mercurial support. The Mercurial support worked quite well except for pushing changes to a remote repository over ssh. A quick look at the Version Control Console revealed that things were getting hung up on: remote: ssh_askpass: exec(/usr/libexec/ssh-askpass): No such file or directory. After confirming that there was no ssh-askpass on my Mac OS X Leopard system, I turned to Google. After a few misses, I stumbled across Joe Mocker's blog post about VNC tunneled through SSH on OS X. Embedded in that post is this shell/AppleScript:

#! /bin/sh

#
# An SSH_ASKPASS command for MacOS X
#
# Author: Joseph Mocker, Sun Microsystems

#
# To use this script:
#     setenv SSH_ASKPASS "macos-askpass"
#     setenv DISPLAY ":0"
#

TITLE=${MACOS_ASKPASS_TITLE:-"SSH"}

DIALOG="display dialog \"$@\" default answer \"\" with title \"$TITLE\""
DIALOG="$DIALOG with icon caution with hidden answer"

result=`osascript -e 'tell application "Finder"' -e "activate"  \
-e "$DIALOG" -e 'end tell'`

if [ "$result" = "" ]; then
exit 1
else
echo "$result" | sed -e 's/^text returned://' -e 's/, button returned:.*$//'
exit 0
fi

I dropped this code into a script at /usr/libexec/ssh-askpass and now when I push from IntelliJ:

Ugly, but it works. Now I just wish that the IntelliJ Mercurial plugin would consult the .hg/hgrc file for the remote repository or at least remember the value I type in when I pushed the last time, so I don't have to type in some long ssh://user@host.org/path/to/the/repo every time.
