for every sub in a group or every group (that the user has
access to).
Avoids sending a long list of sub/group codes in the query string
for no good reason, which is a problem if you like to carry an
insane number of dead echoes or whatever.

iniGetNamedStringList() was returning NULL when attempting to get the list of keys in the "root" (unnamed) section and the file is actually empty/blank. If there were *any* characters in the file, it would return an empty list (not NULL). Now, always return the empty list, even when the file is blank.

As reported by Gamgee (PALANT), the MAILW:0 and MAIL:1 lines didn't display
correctly (weren't justified) because of the combination of colons and dash.
Using MAILW#0-L and MAILW#1-L (replacing colons with hash, ugh) would have
also fixed the issue, but the pipe is the newly preferred method of @-code
format arguments, so just do that through-out the file, leaving the colons.
Help save the colons!
