The first option should be fine. The list that the for loop will iterate through is only evaluated once, so turning it off in the first invocation of the do ... done part should be safe.
I didn't know about nullglob, thanks for the handy tip!

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.

NAME
phones - remote host phone number database
SYNOPSIS
/etc/phones
DESCRIPTION
The file /etc/phones contains the system-wide private phone numbers for the tip(1) program. /etc/phones is normally unreadable, and so may
contain privileged information. The format of /etc/phones is a series of lines of the form:
<system-name>[ ]*<phone-number>.
The system name is one of those defined in the remote(4) file and the phone number is constructed from [0123456789-=*%]. The `=' and `*'
characters are indicators to the auto call units to pause and wait for a second dial tone (when going through an exchange). The `=' is
required by the DF02-AC and the `*' is required by the BIZCOMP 1030.
Comment lines are lines containing a `#' sign in the first column of the line.
Only one phone number per line is permitted. However, if more than one line in the file contains the same system name tip(1) will attempt
to dial each one in turn, until it establishes a connection.
