Fix gettext call

[Marcos Chaves]

Hi,

I read that i18n support is planned for the future, so I run
pygettext.py on mercurial/commands.py (seems to be the only file with
_() calls) just to see if it worked and noticed that there were 3
gettext calls that don't seem to be properly formatted, generating
warnings. Attached is a simple patch that fixes them, so pygettext.py
runs with no errors and all messages are properly extracted.

Patch is attached too, just in case my mailer breaks the lines.
