[gmx-users] grompp bug (system charge)

There is a bug in grompp in the charge count, it will not count a second
line for a moleculetype, for instance:

[ molecules ]
Na 3
Na 2

grompp will not count the charges for the last two Na's.
This total charge count is only used for printing the warning and nothing
else, so you can ignore it.
This bug has been fixed for the next release.

Berk.
