Prevent commit to commit everything

[Harald Kirsch]

Hi all,

in the software system I track with mercurial, file changes appear 
"automagically" after configuration through the GUI. I need to commit 
different directories with different commit messages and normally do

hg commit -m '...' .

Being a heavy svn user too, every so often I forget the trailing dot and 
everything is commited with a useless commit messages. Very annoying.

I tried to use

[defaults]
commit = .

but these are obviously not defaults but additional arguments, meaning 
that the . even ends up in the command when I provide a different 
argument, e.g. just one specific file.

Is there another way to handle this. It would suffice to me if hg 
plainly refuses to commit without an explicit argument.

Any ideas?
