Informix database user password limitations with Lycia3.

Using Lycia3 there is a limitation for informix database user password
defined by INFORMIXPASS environment variable.
It cannot contain a “$” character as any substring after “$” character
is treated as “$whatever” environment variable and will be expanded to its value.
If there is no “$whatever” environment variable then it will be expanded to empty string.
In any case the password string will be changed and thus its value will become incorrect.
