Documentation:
*Non-nil means the gecos field in the password file uses a comma separator.

In the example in `mh-alias-local-users-prefix', commas are used
to separate different values within the so-called gecos field.
This is a fairly common usage. However, in the rare case that the
gecos field in your password file is not separated by commas and
whose contents may contain commas, you can turn this option off.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 7.4 of the MH-E package that is part of Emacs 22.1.
