Oh! EasyPG runs well with howm!
(1) Run gpg-agent.
(2) Put *.gpg into ~/howm/.
(3) M-x epa-file-enable
Then howm can search *.gpg seamlessly.

Below is a quick hack to use external grep and EPG at the same time.
* All files in ~/howm/ are searched by the external grep command.
* All files in ~/gpg/ are searched by elisp so that EPG is applied.
This is necessary because searching all files with elisp is too slow
for me.  Test version (howm-test071107) is required for this code.
