Tiny bug report, interaction between alias and help

Hi, git people.  (My first message here, please be kind!)

Page http://git.or.cz/#community says to report git bugs on this list. This is a tiny bug for "git version 1.5.4.rc3.14.g44397-dirty". If the "bug" is inappropriate, please then consider this as a suggestion! :-)

If, after "git config --global alias.st status", say, I try:

   git st --help

git then replies:

   No manual entry for git-st

It would be nice if --help was interacting better with aliases.

                                       Thanks for your attention,
